Depends who ported the heads. If they were done by some backyard head porter than they are probably useless. The pullies and exhaust will add more power than the B cam. Ford Racing cams are good door stops and that is about it.

Ok what about this combination...

GT40 heads - ported and polished
Edelbrock intake
670 cfm Holly Street Avenger Carb
Accel distributor
Huge aluminum racing radiator
New fuel pressure regulator
Shorty headers
New full dual exhaust (2.5")
Hurst short throw shifter
New Stage 3 clutch
3.73 gears
7.5 rear end but comes
3.5 inch cowl hood
?

HP and TQ.

7.5 rear end. 16" rims.

An will the numbers be different with an 8.8 posi set up since the 7.5 is currently the rear. Tnx in advance.

those ratings are for an 87-93 fox, the car in question is a 85.

1985 hp/torque ratings
210hp @ 4400rpm
270ftlbs @ 3200rpm

they also went 0-60 in 7.2 seconds and ran the quater in 15.9 seconds.

yup, with those mods id say about 245-260. stock heads are junk, ported or not, they are not going to make much of a difference, the bcam is junk, and the 3in exhaust is probobly hurting more than helping you. also on a street car, underdrive pullies are often more trouble than they are worth.

265-270hp and 310ftlbs. again, stock heads are worth next to nothing whether ported or not. this goes for e7s or gt40s. gt40s are simply glorified stock heads. the 2.5 exhaust is a lot better, as the 3in is overkill. and you also listed a lot of mods that will not help you in your quest to horsepower. a 3.5in cowl hood, short throw shifter, gears, radiator, and fuel pressure regulator will help you in your quest for horsepower just as much as putting a bunch of stickers on your car.
