I have a 360-based motor with RHS X heads and Harland Sharp 1.6 rockers on it. I have noticed that the rocker starts outside of the center of the valve and continues outward as the valve opens, almost to the point of going over the edge of the stem (rocker is too long). I am assuming that since I am running cast-in stands there is no way to raise the rocker enough to compensate for this, so what rockers fit the RHS heads best? This is a street/strip engine that will see a lot of cycles so I need to be able to make it live.
