Thanks for the info on the MLS gaskets. I need some info on the GM head studs. I know ARP studs cost $120. Are the GM studs available at parts stores or only at GM dealers? What are the reccomended torque settings for the studs? Must you retorque the studs after running the engine? That would be a real job trying to get that done. Do you use the GM nuts & washers & do they come with the studs? What do the studs & nuts cost?
Thanks for all your help. It's great to have the help of the SC guys.

GM wouldn't sell head studs unless their GM Performance division offers them as an aftermarket part for the 2.8L Chevy V6. If you were to go to a GM dealership for them, they would sell you bolts. This goes for any auto parts store, too.

You can get the studs from Jegs or Summit....

You can use the Ford 3.8's, but it is recommended that you bottom tap all the bolt holes before installation.....

Cost is about $100.00 for the Ford studs......

A little less for the Chevy studs....

Do you use the same torque value as the stock?

45-65-85 lb/ft in proper sequence. Torque all to 45, then all to 65, finally torque all to 85. I would recommend getting the proper thread chaser(tap) and cleaning out the threads, makes it a lot easier. I think the tap is M11x1.5 someone correct me if I'm wrong.

Make sure you use ARP moly lube on the studs when installing them into the block, moly lube on both sides of the washers, and moly lube on threads before installing the nuts.
