Roller Rockers On A 300HP Chebbie Crate Motor

Randy Schonscheck · 03-02-2011, 05:01 PM

I was wondering what brand of 1.5 roller rockers that you guys have run on these heads. Just looking at the different styles, some seem larger in physical size, like a Comp cams , Crane etc compared to the Crower stainless steel which looks somewhat smaller. Will these rockers fit under the steel center bolt factory stock ones, with the shields and deflectors or do you need the GM Perf aluminum ones or other aftermarket ones? The GM ones are about 1/4 inch taller, I don't want the adjusting nuts or anythng to be hitting or rubbing. Thanks!
