The rev kit is designed for solid roller lifters, not hydraulic roller lifters. I'm not aware of any on the market for the Ford engines, mainly SBC & BBC.
Comp Cams sells two styles of hydraulic roller lifter, the Ford style & the link bar style. Which type went into your motor.
What rpm limit did comp Cams quote with the lifters & springs they supplied? Did you use the springs Comp supplied or recommended, or did you use what came with the cylinder heads?
