    Sorry I missed your post been busy !You need to find the valve set marks on the fly wheel peep hole at the bottom, also your engine will have a slack spot where the
    dynatard lump is I beleive there is a small depression at that spot to allow the slave in the rocker to charge
    your probably landing on that spot,Seting on valves rocking is not the best on these engines.

    ok thx i went by the flywheel #s 1-6 #1 push rods were the lowest 6 was uneven so i started on #1adjusted it then rolled the eng.around to valves 2-5 mark on flywheel.adjusted #5 then rolled eng to valves 3-4 mark set #3 and etc.etc. my question is should there be excessive clearence on some ext.valves after all adjustments have been made.
