I got a set of 1.65 roller rockers from a friend. I was wonder if it would work on my LT1. They came off a Chevy SB 350. Any help is welcome.

Thanks,

Is that 1.65 or 1.6 ratio rocker? In any case if they are SA(self aligning) rockers, they will work with out any mods. If they are NSA(non-self aligning) then you will need guide plates installed and hardened push rods.
The SA rockers have flat ground washers on both sides of the roller tip that are larger diameter then the tip. These fit over the valve stem and maintain alignment.

 

They 1.65 roller NSA. I am going to run a .550 coil on the heads with a cam spec at .501 lift.
