Well I went ahead with the ProComp studs. I was quite pleased with the quality & finish of the kit. I installed finger-tight & torqued them to 25-50-75 ft.-lbs. on the 11mm (7/16") studs and then 18-23 ft.-lbs. on the 8mm (5/16") studs using ARP assembly lube & GM MLS gaskets. The only 'issue' I had is that the end of the 8mm studs do not have a hex to aid installation (not sure if ARP's have this or not). I didn't realize that until after I torqued the 11mm studs, otherwise I would have screwed the the 8mm studs in before putting the head on the block. So I locked two 5/16-24NF jam nuts together on the stud and used them to screw it in. Overall I was happy with the installation.

I don't know the numbers for sure, but torque numbers with ARP lube are always lower than plain oil.
