Yup, looked at them, Denny. My machinist is redoing my heads and modernizing them a bit. They will have stainless steel valves with the same stem diameter as a SBC. He has the guides in, now we are looking for the adjustable rockers. I would really like a set of roller rockers, I keep hearing that there is a company making them, but so far no luck in tracking them down. Thanks for the help, I know they are out there somewhere, just gotta find them. Appreciate it.
