Jeff ported several heads for me. He was never very pleasant to talk to, and he wasn't very transparent about the porting work. He wouldn't tell me what he was going to do and sometimes when the heads arrived I wasn't happy with what he had done. I had to have his stuff repaired a few times since he didn't do everything correctly. So I stopped doing business with MCH more than 10 years ago. I never had any transactions with Bob so sounds like I dodged a bullet there.
