I have a cometic metal head gasket for my rb20 rebuild. I understand some copper spray helps the cometic out. I was wondering if their is any recomendations for better sealing of the head gasket. FYI i do already have arp head studs.thanks

Deck the block and mill the head for flatness. Use thicker gasket to compensate.

Exactly I would also if you have the Head off use this op for some head work at the machine shop
