I'm installing head studs on my gsr and want to know the correct torque spec for them. THe sheet that comes with it says to go to 65lbs/ft for aluminumheads. THe sheet also says on it that those numbers are general specs and are not for specific installaltions. SO what is right?

Also one of the nuts came with no threads?!?!? What's the deal with that? I'm still waiting to hear from them about replacing it.

I have arp headstuds as well for my b18c1 block and I torque them to 65 ft. lbs.

Thanks. THis is my first time using the studs and the directions are little too non-specific. SO 65lbs/ft. Sounds good. Also, the washer placement, does the concaved side face the nut or down towards the head? We didn't tighten any up yet becuase were waiting for the nut to be replaced, but we put the others in place and had the washers with the concaved cutout facing up towards the nut.

Okay, seems to be consistent here. Any thoughts on the washer orientation?

yeah 65# and 68# are good. i personally torqued mine to 67# on my first motor, but 70# on the most recent one. and 75# on another motor for a friend. no sealing problems at all. worked great.

as for the nut thing i don't know about that. kinda odd.
