2002 Corvette
-a4
-2.73 gears
-CAI
-Headers
-Exhaust
-yank ss3200 2.1STR (will be ordering next week)
-BFG T/A KDW2 up front, BFG T/A Drag radials out back (next week)

The car is not a DD persay, but my plan is to keep it very civil. I will be running the stcok camshaft (may add 1.8 rockers for higher lift while I still have the stock cam) and in the future when I get a cam, it will still be on the mild side, either a CheaTR or a similar cam suggested to me by Predator Z. My goal for the car is stock-like when cruising, reliable, but nasty when you get on it. I actually was even opposed to a torque converter at first, but have been convinced that I'm not going to improve off the line and low end performance without it. I think the combo of the yank3200 and 2.73 gears will give me the best of both worlds.

At any rate, what head would you suggest for this application, and more importantly WHY?

Thanks in advance!

Also, take price into consideration.

If you can afford the AFRs (or Trick Flows), do it. From what I see of the guys on here, you'll get better results and manners from the AFRs with a stock/small cam. All your options will be a good boost, but I would do it right the first time and not wonder if you could be getting more out of your combo.

Search on Patrick Guerra's TA with AFRs and CheaTR cam, very impressive.

I don't think TSP ported Dart 205's are an option anymore. At least they weren't 2 weeks ago when I ordered my heads.

If money is no object, the AFR's are putting out great numbers (goes without saying).

All I can say is consider your goals and invest wisely. Consider twice++, stroke the check once!

First, I'd get off the 2:73's....Second, if you can spend 2,000-2,300...afrs or teas are the way to go...I'm with the teas, I get my motor Tuesday...I know afr has had the reign for awhile, but I'm giving Tooley and his guys a shot...seems to me they've done alot of research on these heads.....either way with the 2 I mentioned, you're not going to be dissappointed...

I'm in sorta the same situation as you. I went with the PRC stg 1 with the double valve springs and the TRak cam. I too wanted to retain the highway gears (3.15's). I'm having mine tuned Monday and I'll let everyone know how much RWHP it makes.

I voted TSP's Terminators . The heads were designed by the great John Lingenfelter RIP. They are Edelbrock castings worked over to perfection by Texas Speed . The heads have shown there potential 500rwhp capable while retaining a high velocity 200cc intake runner which will help torque production and throttle response . For your application small cam /stall this is the right cylinder head .

I suggest Dart 205s or if you are planning bigger upgrades just get the Dart 225s. I have the 205s and they are great until you pass .600 lift then they start to drop. The 225s have about the same flow numbers but just keep climbing at higher lift.

exSSer

I agree you should probably stay with a smaller port head if you insist on retaining your present gears/cam/A4 combo. I highly suggest if you do the heads, put at least a small 224 type cam in. It will greatly improve your results, and drivability will not suffer at all with a tune. So, as far as heads go, I would say the Terminators/Dart 205s or AFR 205s, whatever your budget allows. I have the TFS/TEA, but also have a M12/3.42 combo.

LSX-Racer

The ETP 215 heads are a solid choice you haven't listed.

LS1 powerplants, with the right peripherals, make great power with these heads. From just off idle to shift point with a very flat torque curve. You'll love them with your automatic and highway gearing. Maybe even take some stall out of your converter choice. A .600"-.610" lift cam with 226*-228* duration at .050 will dramatically wake up the car.

I went with AFR's. Smaller ports - Higher intake velocities = better low to mid range power. I am very pleased with the results. 224/228 cam with AFR's milled to 62cc = 405 RWHP and drives like stock........until you step on the gas....then all hell breaks loose.

I had to vote for AFRs. I have a set coming, will be here Tues actually. You just can't go wrong with a proven product.

BOWTIE

Well, I think your prices are a little misconstrued (sp). If you are wanting to stay with the stock cam or a smaller cam you would not need the TSP heads with the spring upgrade. That would put the stg 1 LS6 at $999.99 with LS6 springs, and the Terminators at $1675.00 with LS6 springs or you might could get some 918 or something else somewhere in the middle for a slightly higher price. I am also in a head debate and considering many of the same choices. I wish we had some more results of these Terminator heads with some other cam packages, perhaps something like Patrick G has.

I voted for AFRs because I've seen tons of good numbers. I expect a lot of good things from Trickflows but I wouldn't spend $2k+ until I actually saw the good numbers. Before you drop $2000 on heads I would seriously consider getting 3.73s (at least 3.42s!) and an aftermarket cam. You can get a quiet, sleeper cam that will improve performance and keep stock sound and feel. I don't know of a cam that is stock sounding/performing while cruising then nasty when you get on it. Usually, a nasty up top cam is going to sound really nasty down low. Anything in the <226 range cam on a 113-114 LSA would probably be very close to stock. Someone correct me if I'm wrong.

Don't forget that for the next week our heads are on sale for $1095.00.

No matter what heads I get, I do want the best springs b/c like I said, in the future I will swap cams, probably a CheaTR (high-lift #s) because my ultimate goal is FI in the next 2 years.

Dead set on keeping the highway gears, not doing a cam-swap anytime soon because every shop near me levies the "corvette tax" I was qouted $2,000 for a head/cam swap and tune by a local shop, which is more than I would spend on all the parts themselves. I know the f-body guys aren't paying this much.

Doesn't a mustang dyno read around 10% less power than a dynojet reads . **** you should make 482 rwhp, 447rwtq
