I tried the search several times, it keeps timing out. What are the torque specs for the ARP LS1 12 pt. head studs?

I also need the specs for the arp main studs.

Thanks!

 

For the head studs...

I used that as a guide but instead used the 20/40/70ft/lb sequence instead of 20/40/65.

MAKE SURE you use their ARP moly lube to get the correct tq readings. You should tq to spec, wait an hour, recheck the tq, let it sit overnight and check again. That's how I've done it and never had problems.

 

I did the 20/40/65
and 22 on the top 5

 

Thanks guys, I will get some of the ARP moly lube. Hmm. 65 or 70. I'll cut the difference and do 67.5

 

Head studs: 70lb-ft

Main studs: 60lb-ft (inner studs), 50lb-ft (outer studs)

All values w/ ARP moly lube.

Thanks Jason, you da man!

 

That is what I used as well with ARP lube. If oil is used instead, the figures can go up by 10.

 

Aren't the specs higher on an iron block also?

 

Not that I know of
