Default Roller Rocker

I just got my heads finished and was looking at rockers. Can I use Gen1 rockers on my LT1 ? I want to use 1.6 roller rockers with 7/16 studs but do not see any for the LT1. If I cant use gen1 does anybody have a part number for the 1.6 with 7/16 studs or do I have to stick with 3/8 studs?

Absolutely. Can't go wrong with a set of these:

Which means you would need guide plates and hardened or chromoly PR's since they are not self-aligning.

Op

as noted, guide plates & hardened PR are needed with NSA RR

Get the 7/16 ARP studs for guide plates

I use the ISKY adjustable guide plates and Trick Flo .080 thick wall PR

Recommended to check for PR length with new heads/cam
