Best carb intake setup?

8.75 Sure Grip 4:11 I have the stock exhaust manifolds but will probablly add headers Dougs or TTI, Target goal would be to get as much power out of the motor without taking it apart, motor was freshend up recently and runs strong but is completly stock as far as i know. Car is being prepped for paint motor and trans are out of the car so i was thinking about updating the motor while it is out looking for advice on upgrades? thanks...
