Cylinder Head 201 - Radius Cut Valve Job
This video covers the complete valve job process that your machinist might perform. If the 100 series videos didn't help you identify and correct a problem with your cylinder head, then this is the next step. This video is brought to you with permission from my machinist in full 1080HD, and covers cleaning up the head inside and out, preparation and setting up a radius cutter, cutting all 16 valve seats, valve grinding, and spans 3.5 hours of actual work in under 30 minutes. There's nothing like this anywhere else on YouTube. THANK YOU BALLOS PRECISION MACHINE. Thank you for the professional explanation and execution of a job excellently-done, and un-precedented access to your facilities. A valve job is done by re-grinding or replacing valves, and then having new seats cut to match the faces of the valves you're using. There are several different machines that might be utilized to achieve this result, but the process is the same no matter how it's done. There are seat cutters that utilize cutting stones. There are valve seat cutters with 3 separate angles installed 120° out-of-phase, and there are single cutters with all 3 angles (radius cutter) that cut with one blade in one pass. The machine demonstrated here is a Sunnen VGS-20 Radius Cutter. This machine (now out of production) produces a gradual curved seat that's superior to the shape of a traditional 3-angle seat. While a radius cutter does contain the 30, 45 and 60 degree angles, it does so without leaving any sharp edges between their faces. My valve selection includes Supertech 1mm oversized nitride-coated stainless steel undercut and back-cut intake valves, and 1mm oversized Inconel back-cut Exhaust valves. Inconel is a high-temperature alloy utilized in marine and forced-induction performance engines that can handle more abuse than steel can without melting. The other characteristics of the valves which are discussed typically yield bigger gains in airflow than simply using a bigger hole and a bigger valve. Why I did this to a perfectly-good cylinder head: I changed cams. Because the valves were previously recessed during another valve job 9 years ago, my valve installed height was increased and this raised the operating positions of my rocker arms. My new camshaft selection dictates using the stock valve install height. The only solutions to this valve install height problem are to either replace the valve seats, or install oversized valves. I opted for the latter.

Looking at my Chevy 383 Ported "Revised" Pro Comp Aluminum Heads rat rod sbc
I was asked what I do to port a set of Revised Pro Comp heads. There are so many things to touch upon but I'll just mention what I did on these to be quick. A little about me,,I've been building engines for 30 years now. I've been porting heads about 20 years. I try to keep up with whats going on and I continually study online. I buy new books and engine building software(Desk-top Dyno/Dragstrip,etc). I'm impressed with the software results. Anyway,,When I saw these heads online I wanted to see just how they stacked up to Darts,Brodix,Edelbrock,etc. I had also read where people were bashing them. Some said they were cheaply made castings, others bashed 'em because they're made overseas. Then later they re-emerged as "New & Improved". I have a friend that sells them online and he built up a 383 and we ported a set and they did very well,,especially for the {lack of) money. When I first looked at 'em I didn't like the areas in the ports that are under the valve seats. I point out the areas at the start of the vid. There are small areas under the valve seats that are noticably machined away. It's nothing to be concerned with as none have ever failed that I know of. There are great photos online that show these heads aggressively CNC Ported,they're so huge that the Intake Ports run into Int bolt hole bosses(I can email you the pics if you need them). Thats too big as they'll have to run sleeves in the mounting holes. Something that I recommend too is to look at the ports online of the major manufactuers of racing heads,,or if available look at ones being built at a local machine shop. When I port a set of heads I make a thickness gauge out of coat hangers. When finished it looks like an "X". It accurately reflects how thick the metal is while porting so that you don't go too far and it helps to get ports consistent ( I'll add that 'how too' later). One unusual thing that I do is lap the valves to the seats with an electric drill motor. It's reversible and takes just a second for each valve and seat to show the correct "grey ring". It takes about 3 minutes to do each head. The results are outstanding with the seats showing concentricity. Most local machine shops just cut the valves, then the seats,,then assemble them. If you do the solvent test they usually leak,,sometimes badly. Thats cylinder leak down,,less power,smoking,blow by,etc. So you get what you pay for. What I mean is that I ALWAYS disassemble the stuff at home and inspect the work. When I find a problem I take it back to the machine shop.Most machine shops don't like a guy who knows how to inspect the work. A good machine shop is really hard to find not just the work but the people there. I know of a few local machine shops in central Arkansas that will do bad work for one customer and great work for another intentially.A lot of times they're racing rivals. Remember, when you get crappy work and run it ~ it'll run crappy or not work,,or last very long. So when you take the stuff apart at home you can see who your friends are. I think it's important to spend your money where the quality of the work is at the forefront of the business.Thats why I drive to a good place with modern machines and trained people. You can have an intelligent conversation and get what you ask and pay for. One more thing,,Try my drill method for lapping the valves,,it works really smoothly.Second thing,,the old notion of polishing the ports has been proven wrong scientifically,especially on the Intakes. They need a slight texture,,look up why.Too much to go into here. Theres even guys who epoxy pebbles or marbles on the bottoms of their racing boats to ride more on air,,reducing friction. On the motor,, I'll start the engine in the next few days and then later toss it into an 86 S-10. It'll have an old school turbo 350 with shift kit and an old Vega Stall Convertor. I can port a set of these heads in a day and a half for about $300.oo The Iron stock type heads are harder and take more time and cost a little more. I've ported about 30 sets now and got to run half of them and got to see how they do. Porting works! and makes quite a difference. Thanks for looking.

Cylinder Head 101 - Remove Cams Rockers & Lifters
Going through a 4g63 Cylinder Head? You're on the right channel. I don't know how many parts there will be to this series, I suppose it could go on forever... We all have different ways of doing it, and I'm going to show you mine. This video won't put a dent in most people's grey matter outside of entertainment value... but I tried to keep it fun. I'd like to leave at least a small dent. But no music in these because they're going to cover a lot of ground and fast. I'm not doing anything difficult. This part of this job really isn't. Most everybody pays someone else to do the complicated stuff for them, and those people do it every day so it's still easy unless you earn your money to pay for it from difficult and degrading means. But this video's about getting started. There's some safety and organization tips to be aware of before diving in. Stuff that could help people whether or not they even own a Mitsubishi. Everything else is in the videos!

Cylinder Head 105 - Valve Job Basics
Valves not sealing? Valves not bent? This is how you fix that problem. In this video I outline the basic valve job procedure. Cleaning the valves, cleaning the seats, cleaning the combustion chamber and lapping the valves in to make a better seal. Here I cover the process start-to-finish. It's the same exact process for pretty much all non-rotary combustion engines. It takes patience and perseverance to do this job, but anyone can do it. Reference your service manual for measurements and service limits. Everything else that's not in your service manual is in this video. I apologize for not having broken busted crap to work with in this video. It's more beneficial to all of you when bad fortune falls on me because it gets well documented, and many people watching these videos are looking for answers. If you have bent valves, you will discover it quickly once you chuck one up in the drill. You'll see the face of the valve wobble around while it spins. You'll see evidence of this damage on the valve seat. If it's bad, you may see damage on the valve guides in the form of cracks or missing pieces where the valve guides protrude through the head ports. Give all that stuff a good visual inspection. ...and if you doubt yourself, never hesitate to get a second opinion or consult a machine shop. They will have access to expensive tools that you wont find in your average gearhead's garage.
