the efi was screwed up to.four bad sensors,and leaking injector.with rockers doing there thing i am surprised it even ran so good.its not out the woods yet until i get the pushrods in lol.i found the problem when i pulled the valve covers to just make sure everthing looked right on the valves.well i took a rocker loose and was looking at it and noticed it it was catching on the stud for rockers.i never checked the push rod length.i assumed since i didn"t change any of the gemoentry it would have the same length pushrods.well dumb ass me for got that i added in guide plates and it moved the stud up .0050,so that puts the rocker down more on the rocker stud.check it with my pushrod length tool and sure enough it was .0050 short.let this be a lesson always check your pushrod length.
