Torqing ARP head bolts w/o moly lube?? - 07/06/09 07:48 PM
I'm trying to torq down a set of 440source heads, their instructions say to go to 60ft-lbs, however I don't have the ARP lube. How tight should I go with just 30w motor oil? The back of the box says I should be in the high 70's but curious if anyone else has done it w/o their moly lube.

Why not go get some moly lube?

With stock heads ARP says to go from 90lbs with moly to 130 lbs with oil. So I would think you will need to up the torque to what ARP suggests.

I am curious about this also. When I went to the speed shop to get the ARP grease they said to just use any moly grease. Sixty ft lbs seems a little light but thats what I will do unless I find out something different.

The ARP web site has torque specs for motor oil as well as moly.
