I've spent most of the morning looking at head gaskets for this thing. I'm going to put ARP studs in it but I really don't need a thin gasket. Just want something that's going to hold the extra cylinder pressure. Also most gaskets say they will work for 318 to 360 but I'm assuming that's only because the bore hole is larger than my little 4" hole. Any thoughts on a good gasket before I pull the trigger?
