GT40X are pedistal mount rockers. 1.6 or 1.7 ratio kind of depends on you cam choice and clearence issues.

I put in 1.6 and studs. Their stronger and easy to adjust. Plus no clearance issues with valve covers..........the studs are stronger than boltdowns.

I belive it depends on which size stud you go with. I think 93pony posted earlier that the pedistals were stroner than the 3/8 stud but not stronger than the 7/16. I am not sure where he got his info. I know Ford Racing told me pedistals would easily handle 350 psi open springs.
