IIRC Cometic or ARP says to torque the head studs down to like 75 lb-ft using their moly lube. I know you guys recommend an extra 15 lb-ft to help the Cometics seal up better, and ARP recommends a few extra lb-ft when using oil instead of moly lube.

I'm going to be sealing the Cometics up for the 3rd time this weekend with my ARP studs and 20W50 oil. What do you guys recommend that I torque them to?

 

90, I would be leary about using them a third time but thats just me.

 

You wont have any trouble with ARP and 75-80,I build these things all the time and have done it both ways.NO problem either way.Make sure the threads have lube or the torque wont be correct.Make sure all studs are seated or bottomed out.If this is an aluminum block do not exceed torque recommendations.
