Honestly I don't know where it gets his master's. All I can say is I've had good results. But in my personal opinion I only see both of them regrinding any spec they wanted to in the world. Out of any cam. I can't imagine calling Ken with any spec I wanted and him not just saying, okay. Maybe Bullet has an owner you can talk to or maybe that's a big company with people answering the phones? I know with Ken you will personally talk to Ken who grinds these cams and races the cams and probably have driven in cars with most of his grinds. I mean I have no objections to driving up there with my car right now and letting him feel difference between the old cam and the new cam. But after all these years I'm sure he knows exactly what it's going to do. More of my-2
