I have a set on a 410, thats still running and functions just fine. I had a cnc'd set that I had issues with the helicoils on the rocker stands which caused all sorts of headaches.. BUT.. the cnc'd ones did yield an 11.8/112 @ 6000ft DA rolling into the throttle. I will fix the stand issues and probably use them in a different build with a hyd roller cam instead of a solid roller.
