Rocker Arm?
I am in the process of upgrading my stock 350 TPI motor. The motor will have an Accel intake, ASM runners, and ZZ4 cam. I am leaning towards 180cc AFR cylinder heads. My question is that I was planning to use a set of Comp roller tip rockers but I see AFR does not recommend using them. What would you recommend? I want to keep the centerbolt valve covers preferably stock height.

I already have the cam. I am not sure why afr does not recommend the rockers unless it has to do with spring pressure. The magnum roller tip rockers are only rated to 350 lbs. and the springs are 360 lbs. at .600 lift.

Yes that is what I saw. I see several companies make narrow aluminum rockers that are suppose to clear centerbolt covers. Plus I am concerned about the aluminum rockers not lasting. Just wondering what others are using so I don't purchase something and find out that there still is issues.

Re: Rocker Arm?
OK, so AFR is saying they want FULL roller rockers, not just roller tips on a stock style rocker. So it's difference in the fulcrum that they are worried about?

Re: Rocker Arm?
This is the response I got from Joshua at AFR when I questioned them
The reason why we highly recommend full roller rockers is for less ware and heat on valve train components.
Roller tip only rockers tend to cause premature ware on the valve train and create heat do to friction.

Hope this helps.
