Do not run or rotate this engine anymore until you pull heads and correct retainer to guide clearance about .060, check for coilbind, and check piston to valve clearance. It is not normal for pushrods to go thru stock rockers with that cam. I have done it, and gone thousands of miles no problems with that cam and correct springs.
