Doing a Heads/Cam Setup. Need HELP
Hey guys,
Im doing a heads/cam setup over winter for next summer. I called up Texas Speed and they told me about the milled 5.3L Heads that they just did. Did anyone hear anything about those yet the new setup? From what Texas Speed said they should perform better in the mid-range than our Ported LS6 heads. Im going the sleeper route with a stealth Speed Inc. Cam and I'm looking for heads that will not have to give me most HP but will have to have the TQ. I will do a Ported FAST90 and also TB, headers and of course pully and all the bolt on stuff. I need to decide on heads however. My goal is to run 10s on motor since im doing 11s stock. I do have nitrous and will spray down the line when I master driving on motor.
Give me any feedback you can I'm on the virge of pulling the trigger on these 5.3L heads and dont know what to do.
Thanks

I'm not sure, but I think the 5.3's biggest advantage, other than low cost, is their smaller combustion chambers. This allows for higher compression with less milling. This in turn gives you better PTV clearance, which isn't really a factor if you're going with a "stealth" cam. Texas Speed has done some great combos, but I'd go with aftermarket castings for the most performance gains.

If you have the funds go with an aftermarket head such as AFR, Trick Flow, ETP. The AFR's are a proven head with results to back it up. AFR is also a company that stands behind their product. Don't look too much at peak flow numbers either, Flowbenches don't win races.

Talk to the local tuners here in Chicago to also get feedback and look to do a lot of research before you pull the trigger. Have you been to ls1tech.com as the LS1/6 internal motor section has A FREAKIN TON of info on heads and cam installs, etc.

Larry from Speed Inc is a good personal friend of mine, he was the one who piloted the first Stealth Cam in his Z06, I drove the car multiple times and I can tell you that it drove like stock and made great power (close to 420 at the wheels if I remember correctly) with just the cam, long tubes, crank pulley, Blackwing, 3.90 gears and tuning. I think he went 11.30's with this combo on a MT Drag radial in less than ideal weather at the track. I would think with a set of heads and some good driving you should be able to hit the 10's
Plan on a clutch swap as well, Larry had the LS7 clutch in his Z06 with the setup I mentioned above and had zero issues.

Give Ron @ Vengeance Racing a call. They've got some Trickflow/Ported Fast 90-90/Cam combos making 500rwhp. Just click on my sig pic
I'll be going in for a cam swap next month, shooting for 420+rwhp with one of their own Cams.

If $ is no object call ECS and or Vengeance Performance as those trick flows are making great power and are hard right now; otherwise can't go wrong with AFR 205 Mongoose heads and TSP and PAtriot Perf and Livernois out of Michigan offer great flowing budget minded LS1/2/6 heads at a great price!
Also, there are always great heads at an affordable price for sale here and even more better deals on ls1tech.com under parts for sale.

Just called cartek. They suggest their 2x heads for the cam Im running. (the cam is a Speed Inc. 007 CAM specs are: 228/222 588/581 114.5LSA) I know a lot of you guys are saying to go with TrickFlows and now its between trickflows and Cartek. What do you think??? With this set up cartek said i will do 10.7-10.8s on 1/4mile. Will I do better with trick flows???

go with the trickflows, I just had some awesome results (info in the performance results section).
They come assembled with dual springs and all you need is harland sharp rockers (another quality piece) and you are good to go.
