That's a goodun! I tell you man, with a camshaft of that size, you need to contact Mike at @B3RE B3 Engines and let him walk you through how to properly locate your rocker shafts. You will NOT regret it. I tagged him so maybe he'll chime in, but if not, here's his web site with contact info there. I would consider it imperative that you do it. It's WELL worth the money!
