Looking at buying a set for GM LT1 castings and wondered what most were using and a part umber would be nice also. LMk later Clint

 

I know both Jesel and T&D have them. Jesel PN KSS-336060 will work.

I just got me Jesel rockers in yesterday. Started mocking them up tonight to get a pushrod measurement.

I used the KSS-336060 (1.6 ratio I and E). The only problem I have run into is that they dont fit if you are using head studs. The studs stick up way to far to fit under the rocker stand. Jesel includes 8 new head bolts (4 for each side) to be installed. They are a torx head with a slim head to fit under the stand. They also included the torx bits (not just a cheap crappy tool either).

They also include a .100" shim to use if you are running longer valves. Using those its possible the studs would have fit if I machined off the top threads because the rocker stand looks like it cleared the nut. I opted to just pull those studs and install their bolts.

Other than having to pull those studs I havent had any problems. they seem to fit well. I am ordering new 3/8" pushrods tomorrow, but thru my mock ups I dont forsee any more problems. Dont have valve covers to fit yet either but I think I am going to get the Summit brand fabbed covers and drill my own breather. Should not be a problem with those either.

 

I researched this extensively when I had my AFR heads.

DRE rockers. Give them a call, you wont be disappointed. Price is competitive, all their rockers get all the goodies, and they will custom build/custom set them up for your heads.
