Now you can no longer claim that. I will tell you it's happened to me. A filled hydraulic lifter is not easily compressible, you have to let it bleed down as you tight down on it. You reef down too quick on the rocker and the lifter will not bleed down fast enough and you will bend the pushrod, BTDT, and it'll pop out on you when you are leaving the doctor's office with a sick kick and zero oil pressure because the lifter is now setting in the valley and all the oil is dumping back into the crankcase. That is why Comp tells you not to do that. But hey, what does Comp's experience and engineering mean against an opinion anyway.


You are not any more likely to bend a pushrod when installing the rockers on an engine with pumped up hydraulic lifters than you are installing them on an engine with a mechanical cam/lifters. If you bend a pushrod installing rocker arms - hyd or solid cam/lifters - YOU WEREN'T PAYING ATTENTION.

Like my buddy who was putting pushrods in a 06 Malibu.. me: "you making sure you're putting the longer pushrods on the intake?: Buddy: "yup". Me after he started the engine: "dumbass".
