Head bolt torque spec question
 
Factory torque spec for heads studs is 21.-23.9 ft lbs.
ARP says 38 ft lbs for theirs….anyone know it’s so much higher.

So they are still pushing 38ftlbs when they previously acknowledged 28 was the more appropriate specification?

Thanks for posting old discussion.

Just what I needed.

That post/account has been reported at least a couple times. Still here. These clowns keep the mods busy I suspect.
