Ok I understand how the spacing could b different but why would I need to stud the head??? couldn't I just remove the rocker arms and use my rocker bolts to bolt it to the head right over the valves??? It just seems that stud mount is irrelevant in this situation because either way theres gonna have to be holes in the compressor for the studs to go thru so instead of placing the studs there put the rocker bolts...
