As long as the intake ports at the heads are the same size or smaller than the head ports your good up
I would mark the lower half that is bigger than the top and take the top off so you could grind those ports to be the same size or bigger than the top wrench up
You don't want any lips sticking out into the air flow, it causes reversion and reversion causes air flow standoff and turbulence and disturbs the air flow tsk
BTW, some of those intake had the bottom cast big enough so you could grind some of the excess material out of the bottom ports at the heads so you could make them work on Max Wedge port heads devil Does yours scope luck
