The ticking could be a loose exhaust clamp nut. Make sure they are all tight. Or, your cam chain tensioner could be weak. APE makes a manual one. Or you could have a valve out of spec. Do like Hub says and try to isolate the noise before making any big decisions. As far as the valve cover, if you have the manual, do it yourself. it's a good way to get acquainted with your new baby.
