Just follow the directions that come with them and you will be fine, no need to piss your hard earned $$ away to have them checked. They run fine outta the box!



Yeah, that works wonders until you find out that someone forgot to clearance the guides or lube the valves before they out them in the heads. I have these problems (just to name a couple) in many different manufacturers heads. When I was inspecting heads, it was 50 bucks for the inspection if nothing was wrong. THAT is cheap insurance.
