Port match intake/gaskets/heads or not
Like RRR said, there's not much to lose. In general, more unobstructed air flow = more power.
The only thing you need to try and verify as best as you can is how the ports between the two parts line up. Obviously you need to be able to see both mating surfaces with the intake on but since it's almost impossible to do that 100% accurately you need to make some sort of reference mark or impression on either side so you can see where things are.
This is an old Holley Strip Dominator I "gasket matched" several years ago. Don't know if my handiwork helped or not but it looks cool in the pictures. I went as far up into the runner as the burr shank would allow. YRMV.
