Can anyone tell me what the torque steps are for ARP head bolts on the LS1? I can't imagine it is 22lbs + 90* + 90* like it is for the TTY bolts. I would think the sequence is the same. I'd be glad for a link to a relevant post, but I did my search and didn't find anything, so now I'm asking.

No, no....

Torque in sequence, but max torque is 75ft/lbs with arp moly or 85ft/lbs with 30wt. oil.
I torque mine 45-60-70-80.

Some over torque to 80 with moly.

ARp says 70 ft/lbs. Most people I know do 75ft/lbs with the ARP lube. The top smaller bolts are 24 ft/lbs I believe. It should say on a yellow piece of paper in the box.

Yea, its like 70 ftlbs with moly lube, 23 w/ moly for the small bolts as well.

No degreeing afterwards.

I didnt know that.I know the stock Ls1 head bolts are TTY(torque to yield)so you have to use an angle guage.
