Roy with all due respect the A/C pump must be pulled to gain access to the L/H valve cover I dont mean to bitch but its 108 in the shade and i dont have any.I can determain what stroke #1 is in by using a compression gauge or my finger while my girl turns it over.My ignorance lies in not knowing why the Chilton even bothers to mention to rotate the crankshaft 360 or 1 turn before starting this R&R. If its NOT relavent what are thos bozos thinking.Again the distributors out,both sprockets out,engine is at #1 compression stroke...install the sprockets at 12/12 rotate it 360 and stab the dist at #1 cyl.OR install sprockets at 6/12 stab the dist. at #1 cyl. and forget the rotation ?C'mon man its fixin to get dark !

loosen a/c , take off valve cover. tighten a/c. ( make a splash shield for oil and put some cardboard down underneath)start engine. let it warm up... loosen each rocker till it starts clattering then tighten 1 complete turn. its messy but its alot less of a headache then other ways. shut down loosen a/c replace valve cover retighten a/c and do you best to clean up the mess... another great designing flaw from gm!!!! good luck
