ARP headstud torque specs with TFS Alum. heads

ncontt · 01-13-2011, 03:33 PM

numbers I'm seeing on the net say 65 ft/lbs....that seems awful low....is that what is generally accepted?

Thanks in advance....

7/16" head studs, I go 70 ftlbs on all 10 of them (each head), then add another 5-10 for the center ones that are under the valvecovers.

Coupe sounds right

another stupid question, but do you go straight to 70 or get there in a couple stages?

i would go about 50 first on both sides then go to 70 on both and then add the 5-10 lbs in the middle

Stages... I do 30, 50, then 70 (each step on all of the bolts!).
Then go back and "click" to 80 on the middle ones (under valve-cover).
