I have a '57 chevy with a '95 Lt-1. I want to modify the stock engine with roller rockers. I have the center bolt valve covers but not sure what size to get that will fit the stock valve covers i have already chromed. I put a K& N filter on it with a 52mm holley TB. Any ideas? usa:

 

NArrow body, self aligning 3/8" stud roller rockers fit under the stock valve covers with no external modifications.

I used the Crans Gold in my car but lots of guys use the Comp Cams rollers. Part number for the Cranes rollers is 10758-16.

 

Or you could get the GM performance parts 1.6 rockers that come in the hotcam kit as well.

 

Still new at this upgrade thing, but what advantage does the hot cam kit have over the cranes roller rockers for a '95 Lt-1? How good is the MSD opti-spark have over the stock one?

 

From all the bad stuff I've heard.....I would steer clear and stick with the GM opti

 

The roller rockers from the LT4 kit and grane gold rockers are the same thing...bolt made by Crane. The Gold ones are, um, gold, while the gM's aren't.

THe MSD had a rough debut but it appears that MSD has gotten them sorted out. I still runa GM stocker and have not issues..knock wood.

 

Thanks for your help. It sounds like to stay with stock stuff as much as possible for the electrical side but the mechanical side there are all sorts of options. Would it be advisable to replace the camshaft for a beefier sound along with new roller rockers since having to dig into the intake manifold anyway? If so, what sort of cam goes nice with crane rollers?
