Im running the Crane Golds myself with a hydraulic cam. Im gonna be in the market for something reliable with a .600 ish lift solid roller for the same type of conditions. I can definitely see where a solid spacer would be necessary when spring loads get up there as well as rpm. So Harland Sharps= $700 or Comp Ultra Pro Magnums= $700 are basically what you guys would trust in these conditions?

Mopar to the bone!!!
