Roller Rockers Geometry

The target is to try to get the wear pattern in the mid of the stem. If the pattern is on the intake side of center you raise the shaft.If the wear pattern is on the ex side of center you lower the shaft (which us mopar guys cant do) so we use a lash cap.Geometry is important but more with a big bump stick.Sometimes you have to get the best you can and leave it.Take pic with the wear pattern.Also the factory never ck this even on the HEMI.The roller is more forgiving because it rolls not rubbing the stem.
