What happens if you put a non Max Wedge intake on a Max Wedge head

we added some matl to the port flange of a alum intake for running a single carb set up on my iron stage 3 mw headed rb . welding and then machining it was done in house . but later we went with the stage 3 crossed twin fours . even the new motor will run a new twin crossed fours from mopar with ported stage 6 mopar alums on a b block . i could dig it up and shot a pic of the mod , if you like .
