Highest flowing sbm heads?

Who did your repairs initially? Just curious.
I sent the head to Larry Demers in Carrol as he had a guy that had brought brodix heads back from the dead as he stated. Cant recall the guys name. Warren Johnson once flew with one of his cylinder heads in a carry on bag to have it repaired there :). I did talk with him after the repair attempt and he’d said he’d never seen a head so poor. He was a bit disappointed that he couldn’t do anything with it and didn’t charge me a thing for trying which I would have gladly paid.
