Roller rockers?

I have been thinking about installing Comp Cams pro magnum roller rockers on my 94 are there any noticable power gains has anyone tested them on a dyno?

I believe rr's are good for about 15 - 20hp at the crank, if you go w/ 1.6's

If ya do the 1.6 rockers, ya gotta do the valve springs too.

They're a great choice, since they're vastly superior, full roller design and rebuildable to boot. You wait to see them - fantastic quality, and built like an army tank.

I was not aware that you had to change your valve springs?

Was just thumbing through the Comp Cams catalog today and they have a set of roller rockers designed just for the centerbolt SBC valvecovers. They are available in self aligning and non. No prices.

You do, the stock springs are already close to their limit with 1.5 ratio rockers and the stock cam. If you're just going to install the 1.6s and keep the stock redline, the LT4 springs are a good value.

Not that I'm aware of, for LT1/4. Lots of members have these rockers on their L98, so I think it's ok for all the aluminum headed C4s.
