Default What head gasket?
I am doing a lq4 390ci swap for a turbo. Im going to put my 241 heads on for now untill i can afford some as cast trick flow heads. So what head gasket should i get? Also what head bolts i know arp but what exact bolts do i need? Im going to be putting either an 88mm turbo or a 91. I want to run 20 pounds of boost but i understand the 241 heads cant do that reliably. So i will run boost around 14-16 pounds. Thanks guys.

LS9 gaskets and ARP studs. The studs are block specific, not head specific, so be careful when ordering.
