Head bolt torque spec question

[zztot]

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.
Pretty sure my information is “old” so going with more current level.
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.
