Thought i had a broken valve spring so i swapped them with hd springs from autotech. Had to rig up something to block the intake port so that we could push down on the spring and the valve would stay up. My cousin is credited with this "schwaben" knockoff hahaha. Got to the last valve retainer....and it shot past our heads at about 100 mph we searched forever with flashlights on our hands and knees. Were never gonna find it so now im hunting for a local valve retainer to me. Once i find one ill be continuing to put her back together and praying it doesnt tap anymore. It didnt sound good befor
