Hey all, I've contacted ARP about making some head studs out of better material than the currect offering(8740 Chrome Moly 190,000psi T/S), so we possibly won't stretch the studs under moderate to high boost and lift the heads so easily or blow head gaskets for peace of mind, the two materials we are researching for numerous reasons I won't get into are ARP 2000 material at 220,000psi T/S at about 10% stronger, and also Inconel 718 material at about 250-260,000psi T/S, I'll have pricing on both and will post them ASAP, to make this cost effective we need as many people as possible to bring the price down to a livable level, I had them quote me for 5 sets and also 10 sets, 10 or more would be great, I think the price would be pretty good and the quality of materials would be quite a bit better. For reference the C5R head studs are about 250,000psi and go for $920 for the 20 large(11mm?) studs only, no small studs or nuts and washers. So, lets get an idea of how many are willing to commit and go from there.
