Well the rocker arm stoppers instead of just letting the rocker jump, they are holding the rocker in place. But what happens in the head (collapsing of lifter pivots from low oil pressure) should technically just let the rocker slide out under the stopper. Then the stoppers just get in the way and create problems.


SR20 HKS Head stuff isn't that great. Matter of fact... there are probably very few HKS parts that I would run over stuff from other companys.

-Their Cams are really mild compared to other companys like Toda and Tomei. For example Tomei 256s are bigger than HKS 262s.

-Their Valve springs are the all the same specs as OEM Spings.

That being said, your friend could make 380whp on the stock head and the HKS stuff won't hurt. but there is better stuff out there.
