PROFORM RR's

anyobody have experience with their all aluminum 1.5 RR's. I guess they recently came out with a narrow body version that is supposed to fit under the stock centerbolt valve covers....pt#778-66914 (Jegs)

they specifically say "for centerbolt valve covers" on the 1.6 ratio RR's but dont mention it on the 1.5's. I want to keep the 1.5 ratio b/c my valve springs are about maxed out as it is with the cam alone.

So, do you have them and do they fit without modifications????

Just put a set on the TPI'ed 4wd Tahoe I built for a buddy. The 1.6's though. They werent specifically for centerbolt, just 1.6 self-aligners. Went on fine, stock vc's. Probably not gonna last all that well on a daily driver though....

well, aluminum roller rockers aren't known for lasting too well in a continuous run situation, and the proforms' are cheapy aluminum ones so.......

I have them on my lt1. After using other roller rockers over the years these are the cheapest made roller rockers i have ever used. I dont think they will last that long. They are built very loose compared to even a summit brand rocker and feel just cheap.. like made in china cheap. you get what you pay for i guess.
