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'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.

He didn't have the chamber cc's on the listing but i emailed him to ask, He said they have 6K on them and he has been master se certified for 13 years and inspected them himself?
Would these be a good purchase for a street car, if so what do you think they are worth?
