Generation IV Internal Engine - Lq9 build

I putting an lq9 into 69 camaro with a 6 speed and 9inch with 3.90 gears....I already have picked up and ls6 intake.....I would like to see 450hp/450tq to the wheels....Would a set of 243/799 heads with a cam and headers get me close to this and still be able to have good driveability or would i be money ahead to sell the ls6 intake and order a new set of l92s and get a ls3 intake...Car will be used for a cruiser but i would like to race it when i wanted to and have plenty of power.....any ideas or proven combos would be nice as i know this has been posted about a million times

SSHT is a baby cam that will make your number goal on a 364 with a set of aftermarket heads or ported 243s

What about the 90mm snout for the ls6.....worth the money on this set up

Sold the ls6 intake and bought a ls3 intake from PinkyPinky on here...what is the throttle size and I will need a cable driven...who makes the best one.....
