If you can find a really good machine shop that builds racing motors they will normally do a very good job on heads. We have a place in Denton Texas called Calvert motors. They have been building engines since before I was born And I'm over 70. The old man is still working in the shop and both sons are there. I just had them do the heads and block for Marine unit for my sons boat. When they were doing the head they called me and recommended putting in different valves and springs. I'm not sure how many of you know about how easy you can float the valves on a boat but you can't do it with this one after they got done. It was not cheap it cost me $600 for a six cylinder head but it was well worth it.
