Back in the days before much thought was given to fuel efficiency, engine parts were cast iron and much heavier and thicker than necessary. In the seventies that began to change. In those days there was so much extra meat on a head surface, you could mill enough off to make considerable compression ratio increases, and of course plenty enough to mill them straight when need be.

With aluminum heads there are quite a few shops that will put a warped head in a press and straighten it. It's not nearly as simple as that because it involves baking in an oven before or after or maybe both, I don't know. But I do know a guy in Dallas that has a high end automotive, one man machine shop and does this on a regular basis.

Good luck,
