ARP torque specs question

I will be replacing the head haskets in the spring as well as putting on a pair of rebuilt heads. I ordered the ARP set for the Chevy 2.8 as most have recomemded.

Now my question. Do I use the torque specs that are in the Chilton's manual or are there different specs since the ARP are not torque to yeild?

ALWAYS use the torque specifications/procedures provided by the bolt manufacturer (IMHO).

Also, IIRC, ARP says to use their lube since oil may change the torque specs.

Just my .02.

its been a few years since i have done headgaskets. use arp's torque specs and get some of their moly lube. refer to your manual to see if any of the head bolt holes need sealant applied to the bottom threads of the stud. i think some of the bolts protrude into water jackets.

Thank you Mike.

When I did thr right side in Aug '05 I do not recall the Chilton's saying anything about needing sealant but I will double check that. The bolts are on my door step waitng for me when I get home.

I have mine torqued at 75lb/ft, but some have gone as high as 110lb/ft. Those people are also running 20-30psi.
