New Mancini Timing Cover Fitment Issue

I would think it would be better to have one a little on the large side in that spot to squeeze the gasket better, than on the thin side. I bet if you bolt it up, it'd be fine. It'll just squeeze the gasket a little more, which isn't necessarily a bad thing. Only one way to find out.
I tried it with a placeholder gasket and prying the cover down from both water-jackets it was just off to get a bolt started.
I think if I just shave a bit it will fit. everything else looks to align and the crankshaft does center in the front seal.

Well see after I shave it with a grinder.
