Sorry, but if I picked up a set of (shaft mounted rocker) heads from a machine shop and the valve tips were not level, that would be the last set of my heads they would ever do. Hydraulic lifter preload can only compensate for so much.
Yeah, I agree - that's why I think I might take them down there just to show them and see what they say.
Unfortunetly, I picked them up close to 4 years ago now and didn't know then what i know now. While I think I am relatively well informed, there's plenty I didn't and still don't know. I missed this one, but I won't make that same mistake twice.
