hi flow combo

Just a few questions for my street combo for a 1988 GTA pontiac.

how much power do you think this combo will make with tuning exaust and cold air intake?

BBK-1714 BBK GM Tuned-Port Billet Aluminum Adjustable Fuel Regulator Kits $59.95 $59.95

CCA-08-501-8 Competition Cams Xtreme Energy Camshafts $245.95 $245.95

EDL-3890 Edelbrock High-Flo TPI Systems $695.95 $695.95

would it be better to use slp runners and not the base (save $)?

Do I need new heads?

The Edlebrock runners are better . Can you post the cam specs ? If it's like the HR264 ...I say maybe 230ish to the wheels ? BTW Isn't that cam a flat tappit? Your 88 is a hydraulic roller if I am not mistaken . I'd get the base and the runners .
