Hi Marc, just out of curiosity whose lifters did you use, were they the original Johnson's OR just Johnson "styles".

If possible look VERY closely at the lifter adjusting nuts where they contact the valve tips, see if they are perfectly "flat" or if they are "radiused" some??

Thanks, Gary in N.Y.

P.S. I'll also come back later with a way to help keep the cam "where it belongs" so to speak! The very simple method will work providing you have no other underlying issues?
