looking for your suggestions for a new intake

[69 Mach I]

I have a Torker II. From what I hear, it is crap, which might explain my unsatisfactory dyno numbers. I have been recommended to swap it out for a RPM Air Gap. Can anybody with experience opine on this:

Here is my build

1969 351W bored .060 over
forged eagle rods
forged Wiseco flat top pistons @ 11:1 CR
Edelbrock RPM Performer cylinder heads 60cc combustion chamber and 190 cc intake valve
Edelbrok Torker II single plane intake (makes its peak hp between 2500-6500 rpm) Holley 650 cfm 4 bbl carb (double pumper with vac secondaries)
stock 80 gph fuel pump
MSD 6AL ignition and HEI pro billet distrib
C6 transmission with 2200 stall converter and a trac loc

Here is my cam grind:

ADV DUR: INT 297, EXH 308
LIFT: INT 538, EXH 534
DURATION AT .50 DEGREES: INT 236, EXH 242 @ 108 centerline

dyno numbers are attached. I am at least 50 rwhp from where I should be. I don't know the total timing or AF for the moment

In additon to the new intake, I am also thinking about bumping up to a 750 carb. A holley blue fuel pump arrives Tuesday. Please feel free to comment or make constructive suggestions.
