I just went through this... I reused the ARP's that came with
the heads. I wanted new bolts but I couldn't find any listed. I thought the really old ARP catalog had them listed. You could call Dutweillers and ask them. That is what ARP did when I asked them about ARP flywheel bolt PN's.
On the head gaskets, The engine builder and I thought about alot of different things to do. They were concerned about the different expansion rates. They called GM and called alot of other people. What we ended up doing was getting "old school" Felpro 1000's. The same kind used in Indy some time ago, supossedly they have some asbestos in them. I don't know for sure about all of this,but they are on there. I just didn't want to go with the stock one's again and trash the motor again.
