I have a set of hemi MP aluminum heads that have been "O" ringed, now want to use them on a street engine. What gasket would work best? Would rings need to be copper wire filled? Open to suggestions. Thanks

Are there receiver grooves in the block? If yes, then I would go with copper head gaskets. Seal coolant holes on both sides of gaskets with YamaBond.
