Well he thinks he found the problem. He pulled the head off this morning to find they were flowed with a 4.5" bore. He was a little embarrassed. Pretty soft on the low/mid. Probably should have left them alone. This was my second pair of heads I have worked on. First set were some iron J heads I had. I got these cheap enough that I wasn't afraid to grind on them.
