    changing valvetrain set up, is .600 lift too much for 220/224?

    My set up right now is 220/224 .583/.583 114 with cranes 1.89 gold rocker arms. We ran into an issue in the upper rpm's and cant necessarily attribute the dip in power at 6k to the rocker arms, but I do know of several other's with the same issue, in the same RPM's, with the same set up.

    So I was thinking of going back to stock rocker arms, and then I figured I would go with SLP's 1.85 rocker arms as instead of dropping the lift to .551 with the 1.7's they would actually increase the lift to right about .600/.600

    Im concerned with ramp rates, as the cam is only a 220/224. I am using Patriot's dual gold springs. And will be using stock length hardened pushrods.

    Im hoping I will eliminate the harmonics issue here, but dont want to create another problem with the valvetrain with the aggressive ramp rate. Opinion's please!
