performer RPM air gap v.s ported LD4B

Ive got a LD4b on my 360 that has been port matched for 4 brl ports and was wondering if it would be worth swapping to an rpm airgap in terms of power and function.

here is the specs.

74 ish 360

.030 trw flattops

block zero decked

mid 70's heads that have been ported to 4 brl intake sizes and the exhaust took as far as i felt safe.

mopar purple shaft "assuming"(.509 lift)

700 double pumper


car has 3.55's and a reverse manual 727

would it be worth swapping intakes?
