SA vs FB intake manifold

Is it worth the effort to install a SA intake on my 85 12a? I've heard they flow better?

Intake question

It may be slightly better due to less pollution attachments but the one to go far if you
can find it would be the 12A RX3 ones from the 70's.

I just took my fb manifold and removed the coast valve. Then I plugged all the leftover holes with jb weld, and then went over it all with the dremel to make it smooth. Worked pretty well!
