If your not wanting to redo the gear At the vary least have the cam drilled and have it Mech. fastened.
Will that require any extra mods to anything else (such as a different timing cover)? By adding a mech fastener, do you just mean them drilling and tapping a shallow bolt into the end of the cam with the timing gear on it so that you can loctite a bolt and washer into it for added assurance?
