Valves and the location of the lock key are a variable, as are installed height and spring cup dimensions (if applicable). It all adds up to check it yourself, IMHO. You can by just rotating it by hand and using feeler gauges, there is a minumum clearance between spring coils required (touching always bad). <br /><br />good luck, just trying to help without throwing out broad generalizations. I had trouble with a combo before that "should" of had no problems either, a xe-274HR cam on GT-40P heads, they were the springs spec'd for the kit but I screwed up the installed height (easy fix by machining spring cups on the head).
