The s2000 has a roller rocker arms setup.. From a article I read this new design in rocker arms reduced valve-spring load by 30 percent.
From this visual the rockers arms look almost identical to a h22a rocker arm.. This my need some more researching... I might go and buy a s2000 rocker and a h22a so I dont have to take one of mine out,, and check this out!
Im looking at that pic jebarco1 posted, well, it appears to me that the s2k cam lobes are narrower than the H22 cam lobes, but if the rocker arm rollers are higher than the arm, then im sure a H22 cam will still work on it, but what worries me is that the height of the roller from the rocker arm is too high and would cause more lift, and i dont know how much farther up the adjuster screw will go.. But thats a good project to research and try, but maybe a little costy. I would want to try it.
