So you wrote the flat head can be milked as much as I want.
Well as you mill more the compression increases.
Isn't there a limit (aside from too much where the valves begin to hit the head) where the compression might be too much for the head gasket and failure becomes more often?
I know. There is always trade off in dependability vs performance. Looking for a "mid" range number to get a little bit more.
So. If I pulled the head, what measurement do I look for to determine how much I can mill it down?
Does one measure the current thickness a dcdetermine how close to a stock head thickness it is at the moment?
What is that thickness, or does it vary?
