Default Fast 78 vs Fast 90 tb/intake on H/C

Is there enough of a gain to go from a 78 tb/intake to a 90 on a H/C bolt on car? I know I`ve seen posts about this awile back. I did a search and found nothing.

I`m thinking I`ll see a decent gain. I can sell my Fast 78 tb get a NW 90 for cheap and get the 90 top shell for my intake and wont be out too much $.
