Roller Rockers Geometry

P.S. You should probably have 2.5 threads showing, if you can't, the pushrods are too long. Shim the shafts up for the correct geometry and then check for the required pushrod length.


I was told by a engine builder never no more than 2 threads always!

The geometry is fine I already checked that. What length pushrods did you use with these rockers?
