4500 Holley Dominators on Mopar M1 Tunnel Ram

I just set a 4500 gasket on an M1 tunnel Ram and it looks like the bolt holes line up if you twist the carb. gasket a bit and open up the opening, there is plenty of material. Not sure if Chrysler designed this to happen but it looks pretty easy to do. This could also be done to Weiand and Edelbrock intakes if you want to convert them from 4150 to 4500 Dominator carbs.
