I have put a few thousand miles on my Comp Pro Magnums without any problem. I got the kit with new push rods. They are very quiet.

The technology in the new C6 really is amazing.
Jim,
I looked at your C6 and it looks great. I like the idea of keeping the same color combo (I did the same, but yellow w/ black top). I have done some small mods to the C6, but nothing too major. Though I have had it on the dyno twice, and a few trips down the 1/4 (12.7s bone stock is cool).

Comp Cams advertizes them as lighter over the valve tip increasing valvetrain stability. The CC ProMags are good pieces.

Scorpions. Made in America, lifetime warranty. However, they wont fit under the stock valve covers even with the drip tabs removed.

I went with the T&D shaft rocker setup. Overkill yes but to me worth it, plus if I ever go to a solid roller I'm good to go.

For a non S/A I've installed many of the CompCams 7/16 rockers. I'd go with those Rick.

Oh......your PM box is full.

If it doesn't rain I'm going to the track today. My guess with a "soft launch" is 11.86@121MPH

I was a little surprised to see BlackHarleyMan say that Tony Mamo advised him to go with aluminum rockers rather than Pro Magnums for the AFR Eliminator heads he's using on his LT4 rebuild.

Particulary in light of Comp Cams claim the chrome moly Pro Magnums are lighter over the valve than aluminum rockers.
