O-ring block head gasket replacement
Anyone have any experience replacing head gaskets when the block has been O-ringed around the cylinders? Do the o-rings need to be replaced/machined? Can I use aluminum cylinder heads without having a receiver groove cut into them?
What's a good thin head gasket out there? I'm looking to raise my compression.
thanks, and

What exactly are you working on ? Which engine ? What type of gasket was on it ? O-rings are typically used with a copper head gasket and most of the time have a receiver groove cut in the head to match.
I know some guys that use O-rings with other than copper gaskets but they are in very specialized racing applications. Unless you have a very thick gasket now changing to a thinner one gives a very insignificant compression gain. In my opinion not worth it when you weigh in the fact that the thinner gaskets do not seal as well over the long term.

I just looked in the Edelbrock catalog. Their gaskets used to be Corteco, not sure if they still are. Their Olds gasket is 4.230 bore and .038 compressed. If that is what yours is you really are not going to gain much.
