It’s a good question, one that I don’t know the answer too but this much I do know, if you call and ask for Jerry Cantrell, you will get him, and he is the owner and the boss over there. He has always been terrific with me on the phone, and I like his workmanship. So I would give him a call and see what he says. He may very well be able to do it.
He has two of my cams right now for regrinding. The other thing I will mention is that he can reface lifters so if you have a set of lifters and you want to do everything possible to avoid a cam failure, you might consider sending him the lifters and have him grind the correct crown for his cam profile.
