Cylinder Head 103 - Deck Tech
How to clean, inspect, and determine what you can do with your cylinder head. Also how WHAT you do affects your oil system. There are many variables at play when you make changes to your cylinder head deck from your oil system, compression ratio, your valve timing and potentially even disaster. 'best not to go that far with it. Watch this video and avoid it if you're building your own 4g63 head.
The differences between this head and a 1g head are mostly related to port sizes on the intake and Exhaust, and different sized head bolt holes. The 7-bolt uses an 11mm bolt, and a 6-bolt uses 12mm. 1g heads have gigantic intake ports, but aside from that, valve geometry, oil system functionality and the service limits are all the same.

Electrolysis Cleaning a Cylinder Head
This was an experiment I did using electrolysis to clean the cylinder head of a 1967 Triumph GT6. The '67s had external pushrod tubes that makes cleaning them up for restoration a huge pain. I came across the information on electrolysis on a Truck forum, where they'd had a great deal of success using it to remove pretty gnarly rust from an engine block, so I thought I'd give it a shot. Total cost of materials was less than $30, since I already had a battery charger. After it was done, the grease and oil were gone, the rust had converted to a black substance that came off with a toothbrush, and old paint and gaskets flaked off with a razorblade. Well done!

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.
