Robbie, if the obstruction is indeed a cut down bolt, in the cam dowel hole, how about trying to knock it out by removing the camshaft, and tapping it nose down against a bench or other hard surface. If that won`t remove it, you could always try drilling it out, at least enough to get a safe amount of pin engagement. It sounds like the dowel pin in your cam was the shorter 2 piece eccentric version, being used with a 1 piece eccentric.
