Need Help with Heads/Cam

I am looking at getting the T-rex out for a more "streetable" (i know this is an opinion) cam/heads setup. I plan on trading the 9" for a 12 bolt with 4.10's and other than that these are my other current performance mods:

Engine:
-Thunder Racing T-Rex cam (243/249 @ .050, .608"/.613" lift, 110 LSA) **WANT THIS OUT*
-Patriot Gold dual spring kit
-Thunder Racing heat treated chrome-moly pushrods
-Rollmaster heat treated adjustable double roller timing set
-Stealth airlid w/ K&N filter
-Jantzer ported and black powdercoated throttle body
-LS6 intake manifold
-March underdrive pulley
-ARP Pro Series rod bolts
-Ported LS6 oil pump

Exhaust:
-Edelbrock Victor Series drag headers: 1 3/4" to 1 7/8" stepped long tubes with merge collectors and off-road y-pipe
-Hooker cat-back

My Goals is to make around 450 HP streetable HP to the wheels with TQ number that are not to far below 450 aswell. I researched cams and have a fair understanding but I dont know how certain heads/cams with match up. I want the price to be as low as possible (who doesn't) but I don't want to comprimise quailty.

Any sugestions on what heads/cam to get and all were to buy would be great

Thanks, Matt

I went with the G5X3, and a set of AFR 205's milled down to 59cc's/ I wouldnt even look back.

That must be sick! But you had to fly-cut your pistons, right?

I'm almost done installing the same heads but mine are milled to 62cc. I'm using a 0.040" HG, and an XER 224/228 114+1 cam. (no fly-cutting)

There's nothing original about my combo but it should work well and do what I want it to; good street manners and good power.

Dart 205s with a Futral F14 cam and the usual bolt-ons made over 450 for my Z06 and had over 420 torque as well.
