We use Scorpion's rockers on most everything we build with stud mount rockers.

Top quality rocker arms and they are made in the USA right in Fla. Lifetime guarantee as well.

I have used that particular 3/8 stud narrow body self algining model a few times on Vortec, LT1 and LT4 engines. It's great for mild bolt on stuff and requires minor modifications to LT1 (remove drip tabs) and none for LT4's except new 3/8 studs for those with the 10mm studs....

For higher RPM or more serious engines your better off with a big body non-SA rocker, 7/16 studs, guide plates and hardened pushrods... but the big body rockers require more mods to make them fit under the centerbolt valve covers.
