but ive noticed and was wondering if anyone would know about the reason for this, but i meusured the valve stems to the keepers because ive noticed that the intake is larger .1120 to the exaust @ .0590 and was wondering if this could be the reason im haveing so many problems.
so from there i have no idea, ive checked everything i checked the cam the timeing of the cam, i check to make sure that wasent on crack. i just cant get this thing to line up. i got some really nice set ups, but the sweep is more to the intake side i would say it marks on the edge. not even close to the center of the stem. what should i do here should i take my heads back to the machenist and ask what the hell, like most of my freinds are saying or am i doing something wrong.
For the second time, forget comp's method, its wrong. You need the pushrod that gives the smallest pattern. What you're doing makes it way too damn long.

Next your rocker arms may not fit right- not uncommon for unique heads.

First try to use the right pushrod length (much shorter) then look into the rockers.
