Torque specs Cometic gaskets, ARP studs, 20W50 oil

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?
