went out this am and looked at all again plus also the old heads as rocker assembly is to fit both. the mounting base on the new heads is about 5/16ths lower than stock and when i take a good close look the roller does not even contact the valve as its so low the side of the rocker actualy hits the spring cap 1st. they fit and look correct on the stock heads, valvepring height also measures close to equal from old to new heads.
