if you get the cylinder head shaved, do you need a thicker head gasket to maintain compression ratio, or is the amount you would change that negligible?

Back in the day it'd give you a nice bump in compression, nowadays many cars are already running plenty of compression so it depends.

Not if you only had it milled to get it flat again after warping it.

Just resurface it and run it

Look up your combustion chamber's dimensions and volume and do the math...
They taught you how in the 3rd grade.

>will removing 0.005" from my 3-4" stroke change muh compression ratio!?
if you have crippling autism

you never want to run a thicker head gasket, thinner seals better. Spacers are a thing, but not because of compression. When you start shaving wild shit like 20 thou+, you run the risk of fucking your timing up if you have an OHC.

Can't mill too far down on an OHC
