If the cam has walked enough Period. I would also say Change your dist gear and Look VERY Closely to the Gear drive on the Cam to the Dist. Also Check The Lobes VERY VERY close.
One other way to mechanicly fasten The gear is to use a 1/4,3/8s screw (allen set screw/ pipe plug style even) At the mating edge of the Gear & cam
No timing cover mods are needed.
God doesn't like ugly.
