You should be fine.
The FMS M9424-V351 is the same intake as the 2981 Vic Jr.

Carb pad height for both are 5.75"
Carb pad height on the RPM Air Gap 7581: 5.75"
That intake PN 7581 (1500-6500 rpm) is the next mod I'm considering and want to lose the Super Vic 2924 (6.25" pad height) I have (4500-8500 rpm).
Not what I'd call a brilliant intake for street driving, although if I were 16 yrs old I'd probably choose that over the Air Gap....
