Head warped?

[Grumpys93]

As I was installing my valves today I noticed the exhaust valves for #2 cylinder weren't sitting flush. Not sure if I should be worried about this or not. I did take it to a machine shop about 6 years ago to have them look At the head and resurface, hot tank. They said it was good. Here are the pictures:

Thoughts? Am I being paranoid? I plan to push 15-20psi so I am very worried about compression lose. I looked at the h23 head I have and the valves sit flush so I am not sure what exactly is going on. I tried different valves and same thing so I know it's not the valves.

I haven't tried it yet but I think it might involve a straight edge and a feeler gauge on the mating surface.

not sure how I could get a straight edge to work inside the chamber. Its just odd that all the other valves including the intake valves sit flush, however the two exhaust valves don't. I may have to look a little closer and see if the opening has any build up from them painting the head.

Looks like the valve seats are not as deep as the other ones. It's fine as long as the valves are sealing and all the machine work was done correctly.

Fyi, head warping won't affect that at all. If it gets too hot the valve seats will actually fall out.

Looks like you need to lap the valves.

So after some measuring I have found that the valve seats are not grounded down to fit the valves. The inner diameter measured 10.055 on the valve seats that protrude out and all the others measured 10.550-600. So they are .5mm narrower. Also if I rubbed my finger inside the valve chamber my nail would catch on a lip. So I went and verified this with a trust worthy machine shop and they will have it fixed for me on Monday.
