Some valve covers can not be clearance enough. I know the Trick Flow Valve covers fit without clearancing, but there is a good chance you will not be able to get those Canton valve covers to fit no matter what you do. Most of the valve covers out there are designed for 93' and older mustangs where the alternator sits way forward.
Had that issue before... Best fix was to cut a 1" square out of the VC to give the alt clearance. Used some Aluminum tape on the I.D. to create a concave area for clearance. Skim over that both in and out with some JB weld... Done deal. The repair is buried behind the alt and needs nada...Mines been leak free for 5 yrs...
well i put spacers behind both brackets and the the pulleys. i cranked the motor by hand a bunch of times and it seems to be in line. i cant start it yet becasue im waiting on an intake spacer becasue its hitting the valve covers. the gray electrical conector is still rubbing the valve cover a tiny bit. how hot do thy get? do you think it will cvause damage? trhank you
