Anyone know the part number for ARP head studs for a Stage 2 with 8 bolt prod heads? I have studs here for an 86-7 GN/T but they're too long. ARP doesn't list studs for 84-85GN/T. Rather, they list the studs as a Stage 1 77-85. Are these the ones I need? With the 86-7 studs I'll have to stack some extra ARP washers. Anyone have a set laying around? All I need are the studs...
