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.
Cylinder Head 106 - Casting & Porting Tech
No really guys, what can I type here? I just went on for 18 minutes without shutting up. I apologize for deviating from my normal format, but we're almost there...
...when I port a head, there will be no voiceover, and it will be a 200-series video.
Trying something a bit different here. Due to the amount of time spent cleaning, I added music. If you don't like the music please mute the audio. It took about 2 hours to clean. Who really wants to watch me clean an engine anyway?
Adam Singer gets credit as co-creator of this track (collaboration). We remixed his fluffy bunny trance song into a nice breakbeat and back to a different trance tune. It was a really good song to work on. He does make some good trance.

How To Torque Cylinder Head Bolts - EricTheCarGuy
Well this was a fun one to make. I believe I covered everything but if you feel I haven't please let me know in the comments below as well as any tips you might have to add as well. I'm not trying to make a big deal about "pound feet" or "foot pounds" I'm just trying to put that out there, the important thing is that you get the proper torque and get the job done right in my opinion, what you decide to call it is up to you.

Testing for Leaking/Bent Valves
--Please Read-- :)
Some of the best advice I can offer you about fixing your car is to search for an online forum related to your car, or even for your specific engine. If you have a popular car or engine, this can be an amazing tool in diagnosing and fixing cars yourself!
1. Get kerosene, gasoline, or break cleaner.
2. Tilt head on its side, with the ports of the valves you're testing pointing up and exposed.
3. Fill the intake or Exhaust ports with the liquid you chose, make sure to use enough liquid to cover the back of the valve head completely inside the port.
4. Look at the valve surface in the combustion chamber for leakage. (Let it sit for several minutes)
5. If there is a leak, you could have a bent valve or just a bad seal. You might have to replace the valve, or just use some lapping compound to lap the valve/seat to resurface.
6. Repeat for the other side if you wish.
7. This is a great time to replace valve seals if you have noticed they are worn too much.
8. If you have any questions, please post them here and I'll try to answer them quickly.
You just tilt the head on one side or the other depending whether you want to test the intake or Exhaust valves. I'm testing the intake valves in this video. I did this way because I didn't have the leakdown test equipment, but also because I wanted to replace my head gasket anyway. I wouldn't say this is the best way to test initially if you suspect leaking or bent valves because it requires you remove the head. Try just a regular leakdown test first. But if you're taking it off anyway it's pretty nifty and doesn't require the leakdown test tools. There are several methods to do this, this is just the one I chose in my situation.

Replacing valve stem seals in 305 H.O. small block chevy from 1986 Monte Carlo SS
I'm putting the original 305HO back in the Monte after taking the ZZ3 out for my Iroc project. This is mainly to make the car mobile but it may end up tagged with this engine for a while. Previous owner reported that this 305 has over 100k miles on it and has been out of the car since 1997. He said it smoked during startup and sure enough the valve stem seals were worn out. Hopefully this will fix the issue.
Cylinder Head 104 - Remove Valves & Springs
Just one of many ways to remove valves from a cylinder head. I haven't seen a valve compressor like this one on YouTube yet. I know it's nobody makes them like this, because this one is a custom hack job specifically for 4g63 heads... but it's extremely effective and easy to use.
Since I don't own a valve grinder, valve spring pressure testers (for installed height measurement), or valve seat grinding stones... there are several services I'm unable to perform myself. But since I can get the head disassembled to this state, it would be easier and cheaper for me to have them serviced by someone who does.
Valve grinding machine time is cheaper if they don't have to tear down the head. You can lap them in yourself, but if the seat's in really bad shape, it will require attention to allow any of those efforts to be worthwhile.
Valve seat grinding if necessary needs to be done with the proper tools, and if the seats must be replaced, then it can get expensive. Usually $20-ish a hole. Sometimes an oversized bore can be cut into a factory seat. I'm ordering a set of valves to see if that's possible.

Fitting new valve guide seals without removing the cylinder head Suzuki Vitara
This is how you can remove and replace valve guide seals with the head still on the engine. Normally you have to have the head off so you can fit the valve spring compressor on to the head of the valve. I had heard of this method but never tried or seen it done before. The only special tool is a piece of string.

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.
Also, click these links for in-depth discussions about oil port modifications for all generations of Mitsubishis, and specifically for 2g head installations on a 1g block.
