470+ hp goal
i think your gonna have to go pretty big on your cam to reach that goal, with my prc 2.5 heads and a mild cam i only put 425 to the wheels. but thats with a ls6 intake. so maybe with a fast 90/90,and something in the 240's cam, and heads similar to mine 470 is attainable. thats my 2 cents.
Did you look at ticks performance polluter head and cam packege it said with that set up thourgh a m6 made 486rwhp and they said you dont have to fly cut the pistens but its pricey when i priced it it was $3500 for everything but it is everything. But either way i would go with trick flow or afr heads maybe ported by tea that should help quite a bit.

my setup can be duplicated on a 346, 364 (I assume flycutting required) and 383 without issue. I bet you make 470 + rwhp if you duplicate my entire setup man. Good luck, thanks for letting me add my 2 cents Cha Ching !!

Well I have 459rwhp with a ported fast 90/90 G5X2 cam, milled 205 AFR's and Kooks LT's with cats and all bolt-ons. So I'd say go a lil bigger in the cam than I did.

Check out AFR's link below with their 224/228 cam and their street 205 heads on an LS1 block with LS6 intake. The numbers are unbelievable. You don't need a big *** cam that requires 4.56 gears to move it.

why is 470 the magic number?? do you drive the car on the street often? b/c if you do, the safest, cheapest, and most comfortable way to reach that goal is a cam and a little spray. That way you can have the power when you need it but dont have the wear of having a 470 hp car all the time. Theres nothing wrong with a little juice.
I'm doing something similar. Patriot Stage 2 LS6 243 heads 64cc 2.05/1.60's, .040" Cometics for 11:1 compression, FAST 92/92 and Comp 224/228 cam. No numbers yet but would just love to see more than 425 RWHP.

Hey man that wasn't directed at you, but more so at the guy posting as if AFR heads are the end all be all for HEADS. In no way am I knocking the afr's I am just saying that I have had both: afr 205's and tfs 215's. They are equally HIGH QUALITY AFTER MARKET CNC"D HEADS. I give both a 10 out 10, but I have to lean a smidgen towards the TFS 215's
AFR 205 10/10
TFS 215s 10.5/10
Either way you go you won't be disappointed.
Too bad you weren't looking for heads when I was selling my afr 205's already milled and with arp bolts shipped for 1875 !!! Thats a steal. Especially since the heads only had 3500 miles after the new seals and springs.

Lots of responses in this thread without carefully reading the posters mods & specs. This car is a A4 car. While I've seen 470rwhp a4 cars before it's not a easy task & not feasible for a street pump gas setup.
The TFS heads or the PRC 215 heads are really hands down your best bet for making anywhere near the power goals your looking at. I can tell you that for a fact. The AFR heads are nice, but they're nowhere near the power output your trying to get to. I sell all three sets of heads everyday & I can tell you I've personally installed all 3 next to each other on a engine dyno back to back. The TFS & PRC 215 heads are both a healthy bit more hp over the AFR cylinder heads.
The advantage the PRC head has over the others is the smaller chambers without running into p/v clearance. We can ship you a 59cc head that will clear even the larger camshafts while the competitors cylinder heads will run out of p/v clearance somewhere in the 62cc chamber area...
We're also testing a brand new bigger runner LS1 cylinder head for stock bores. You'll still be able to get smaller chambers, but the slightly larger valve will give you less p/v clearance similar to what the TFS head ships with.
This was a M6 car. Not a A4 car.
For max effort camshaft I'll put the MS4 camshaft against any competitors max effort camshaft. The across the board power output the MS4 offers has been engine dyno tested time & time again to be the best all out camshaft available for clearing stock pistons...

I here by revise my comments. Do the h/c ported intake and whatever you get to pull 4 degrees timing and add appropriate shot !!! Stalled a4 346 470+ rwhp.....Tall order man, tall order.
Jason is correct about saying you are asking a lot. I guess I somehow missed the a4. Just assumed the car was an M6. Thats what I get for assuming.

You probably assumed that because in a M6 it's very possible, but stinkin hard to do in a A4 car. 
I guess it's all in how crazy someone wants to get though!!!

Well Jason, what about a solid roller cam, something nasty !!! Sheetmetal intake, valvetrain that will allow 8000 rpms, (good bye stock bottom end) 12 to 1 compression and race gas? Would that be enough?
Or should we come back to the real world and just say SUPERCHARGE the damn thing and be done ????? Stalled a4 + D1sc should be more then enough even with stock h/c.
