Copper Gaskets

As long as you have your tune-up right, and don't get into detonation, you should be able to run a stock steel gasket or a FelPro, at those boost levels.
I honestly have had bad luck with the FelPro gaskets. My engine is bored .030 over and it seems to keep blowing out those gaskets every so often. Thus another reason why I decided copper. Is there another brand that makes a conventional gasket for the /6?
