Any one know the final torque specs for the ARPs? Everything I've read on the great-wide internet says 245. But my arp instal sheet says 210. Advice or explaination?
What do y'all torque for injectors? Ford manual I have says 24, ford tech told me 18.This....
Most of the stud jobs we do, they are torqued to 215 using the new torque lube. Higher performance trucks, are a little different.
Dry or lubricated is a huge difference. There is a significant difference in friction (clamping force vs. torque) between lubricants (oil assembly lube, ARP lube, etc.).I didn't think about it being different for lube or dry. Makes since though.

It's a free country, but I don't see any reason to:
ARP is an extremely competent organization.
- Use any lubricant other than that specified by the fastener manufacturer
- Use any torque specification other than that specified by the manufacturer
Plus, ARP head studs are designed to be reused – if they are not overtorqued and stretched. If the manufacturer lubricant specification is used and the studs are torqued to manufacturer specifications, they will not stretch. If alternative torques and lubricants are used, who knows if they will stretch or plastically deform in some way?
But, like I said, it's a free country. Just my $0.02.
