Can I have some input on heads/cam selection...experts and vendors welcome Hello all. I picked up a 2001 SS m6 1LE camaro. It has the auburn rear as well. It's a bone stock one owner 42,000 car.
My goals are a weekend fun car thar will see some occasional drag racing and possibly auto crossing. I want a 450 hp car that has torque down low to be fun on the street as well and not a dyno queen. I'm keeping the bottom end stock for now and anything else goes. I'm looking ford specific recommendations for heads, cam, intake and whatever other supporting mods I may need. I'd prefer to get everything from the same vendor if at all possible and buy a proven combination. My budget isn't limitless lol, but I want quality parts. Also, the cam and valve train have to not need replacement in 10-15,000 miles because the lobe profile beat the hell out of the springs or rockers. I want to do this one time and do it correctly.
Also, the factory CME will be staying so any exhaust work will be from the heads to the back of the car minus the tips. I love that look lol.
Thank you in advance for any help.

Texas Speed will be your complete one stop shop for a heads/cam combo,
intake, T-chain, oil pump, etc. Here's the kit I'd suggest for your power goal
http://www.texas-speed.com/p-3961-pr...m-package.aspx
pair this w/Fast 92/TB and a 1 7/8" header/exhaust...you'ld see 440-450 rw
with a 228r or Torquer V2 sized cam.

I pretty much agree with above, but maybe just go strait for a fast 102. Keep your cam lift down around .595-.600 and with the correct springs your valvetrain can last a long time

Its going be hard to beat that tsp package and price. With that said there are probably better packages out there as far as reliable cam lobe and valvetrain setups and maybe a head with more torque.

Martin@Tick, has some nice cams available, or he can do a custom grind if needed for your application.
Here's some of his new grinds:
223/226 .610"/.605" 111+2
223/230 .610"/.609" 110+2
227/234 .614"/.612" 110+3 (one of my favorite grinds)
231/234 .617"/.612" 111+2
235/238 .621"/.615" 112+3 (stupid mid-range torque)
235/242 .621"/.615" 111+2

Get an angle drill. Put in the biggest bit that will fit inside the header bolt hole and only drill a little bit, just enuf for it to center a smaller bit. Then, using a smaller bit, preferably a left hand twist, to drill down center of broken piece. If the left hand twist doesn't remove the broken bolt, use an extractor. Its possible to fix this without removing header. But be careful.

224/236 110+3 cam (very similar to my 227/235 110+3 and the 227 intake lobe would make more power)
Stock 243's with valve job and milled to 11.0:1ish compression
Ebay 1x3/4" headers
3.5" merge
3.5" cat-back
Fast 78 with opening ported to 85mm
T56 and a 9" rear
Made 444rwhp/414rwtq ignore the spike on the torque trace it was the tach signal going out and coming back in on the dyno.

Heads:
Livernois Stage 3 LS6, Ai 226cc LS6, TEA Stage 2 LS6, or PRC Stage 2.5s. Not necessarily in that order. Of those, the Ai will have the best PtV clearance. And, if I'm being honest on the dynos I've seen, Ai simply makes power. Everywhere with every combo. TEA and Livernois are right there, though, but have larger valves to do it.
Livernois also has a Stage 2 with stock valves and TEA/PRC both have Stage 1s with stock valves. They would all provide ample room for a decent sized cam when milled and will make probably within 10HP of their bigger brothers.
So to me, all look like good choices, but if you want as much power/flow as possible with as much clearance as possible, Ai wins. Plus, you have more spring choices with Ai.
Cams:
Martin can set you up with something good. So can Phil @ Ai, Ed Curtis @ FTI, Allan Futral, or Pat G/Geoff @ EPS. I'd match the compression and VEs. Sometimes that means milling the heads down or running a much tighter LSA/ICL which eats into clearance. So it all has to be considered together. One thing both EPS and Ai provide is cam doctoring services, so if you are ordering your heads from somewhere else, you have the exact specs of your cam to provide to the head porter so you can get it setup for what you really have. Futral provides that as well since he uses Cam Motion cams and they automatically are doctored unlike Comp Cams.

Jake and Martin, that's a wealth of information thank you! I'm researching a lot as the flow of info keeps coming.
My exhaust will be 1 7/8" race headers, custom Mufflex cated 3.5" y-pipe, custom Mufflex 3.5" catback to the factory dual/dual tips. Denny from Mufflex is a long time good friend so all the polished stainless steel exhaust I could ever want is at my disposal.
Also, I'm starting a search for good true LS6 cores with the better valves being that I'm leaning towards a stock casting now.
I'm confused regarding intake somewhat. Keep stock LS6 and port match it? Fast 92? Or a pp 92 ? The fast 102 seems a bit much for a 346ci car.
I'll be using Andy at Complete Street Performance for my tuning. I'm an old school (old fart) hotrod type and will do my own install minus all the exhaust work.
