Intake and port work recommendation

65 GTO hardtop, 3.54 gears, 28" tire, ultra wide ratio muncie. Old Faithful 1.0 cam and 1.5 rockers, unported 87 cc edelbrock heads with old-style chambers. 850 double pumper, doug's headers. Street car.

Engine is 505 CID IA2. I own an unported RPM and unported Torker 2 intake.

Would it be worthwhile to send the heads and either intake out to get port work done? And if so, is this combo too mild to benefit from a Northwind? Should I go all the way to 340 cfm, 325 cfm, how far out should I go if I have the heads ported?
