Off the Shelf 12mm Head Studs
I have been in contact with ARP and they have given me an M12 Stud part number: AU7700-1B.
This is 7.700" long and made from their standard stud material - however being a 12mm shank they should be able to take a lot more abuse and hold a higher torque value.
Seeing as i'm overseas and i'm trying to buy these so they are ready for when i get back, will the extra 75 thou (1.9mm) extra length make much difference?
What is the standard head stud length on the 996 turbo? anyone got one to measure? From the internet i have got 7.625" but i cannot verify it.

Thanks Sean, I asked them for dimensions of the threaded lengths but got no reply. I guess I can just buy one and see how it fits in my old cases. Don't know if anyone has actually tried them before.

The ones OP is looking at are the basic 8740 chromoly the set with washers and nuts will run about 450ish and ARP2000 will run about 650ish.
I am going to run a set of the ARP2000 studs in a 1500whp motor and see what happens.

Sean, is AU7700-2B ARP2000? That was the PN i was given initially but couldn't find them online, only the 1B.
The correct nut for 1B is ARP-300-8308
Plenty of washers available

With all of the many part numbers ARP has it makes sense that they had another number that would work on our cars! I really look forward to hearing how this works out as it sounds like it's cheaper and readily available

any of you guys have these installed and tested?
#12
that would be just for the cases. the heads and cylinder housings have to be machined on a bridgeport or cnc machine

Sean at SRM told me to torque them down 10 ft lb at a time each pass, using the factory advised pattern until you finish your last pass at 85 ft lb. So you might start at 15 for your first pass and go from there. I did things a bit differently and used an angle torque after 60 lb ft to finish, I have that info in my build thread.
