I'd never think about buying heads complete from even the top 3 companies without having gone through them.

I still stand behind , getting cylinder heads bare, and going thru them. The simple mistake of recieving a set of afr heads as full force tim did, ready to bolt on for a mild hyd roller engine, only to accidently stumble on the fact, they had solid roller springs with over 750lbs or whatever open pressure. We can talk about fancy valve seat cutters, or whatever equipment used, but at the end of the day, something as simple as installing the proper spring, was overlooked.
