If u r on a budget port stock heads or go with l92 heads. U will probably see up to 30hp. May cost about $1,000 but someone can chime in on that. Now if you want to do it right the first time and spendthe money go with trickflow. On my setup I gained 60 hp but it cost $3k for heads, mill work, rods, and rocker. To me it was worth it. It woke up my ls2 and turned it into a beast. Lschelm on here did the same heads As me and so far he loves them. So if money is in your mind, port or l92. If power is on your mind then do trickflow. You get what you pay for.

Are L92 Heads cheap.
The L92 Head is the ECONOMY way to go for HP/ TQ or is it ?
The only you make out doing the L92 Heads is if you do the work yourself.
Yes you can get a set of L92 Castings & Valves for about $1,000. Then if
you are running A Cam you need a set of good Springs. $300.00. then you should have the Heads cut for Compression. $ 200.00. Then you need to have the Pistons Flycut to be able to run a nice size Cam. $ 400.00 ? My
point is all this stuff costs Money and if you add it up the TF's dont look
so terribly expensive and work well with the FAST 92/ 102. For me all I had to do is bolt the Trick Flows on using a very mild Cam to get to 500 RWHP
and suffer nowhere in the Curve.
I see fully prepped sets of L92 and 243 Heads out there for $ 1,899 to $ 2,300. Why would anyone want to buy them when Trick Flows and AFR's
are out there for $2,500.00

and you have your stock heads to keep or sell, but the main thing is the TFS are proven, and you can sell the TFS for a lot more money then the others if you want to put it back to stock

Plus with the L92's you need a new intake manifold and rocker arms.
Lingenfelter price is right considering you are supplying the castings.
Everyone loves the TEA ported TFS heads. Why not look at their porting of your stock castings. They know air flow. Good bang for the buck, and you don't have to change anything to accomodate them.

rwhp = 409.56 & rwtq = 396.28
That was on my 07 Z51 A6 with the paddle shift. I have heard that the A6 eats up some of the hp, but it is a well built trans. I have over 91,000 on my car with no problems. Below is a pic of the dyno list, I was second on the list from the top (Pete).

The last time I Dynoed it was at a Dyno Day at ARD Advanced Racing Dynamics, per the Dynojet Winpep 7 sheet:

You will hardly notice 20-30hp. Go with a low boost supercharger (4-5#) It will make three times the power with the same reliability. I have seen complete systems installed and tuned for roughly the same price you would pay for heads, headers and a CAI.

Man, I wish they had a discussion like this in the C5 section. I would love to talk to someone who could help me with balance/ I have a great mechanic but his forte is making high HP and drag racers. Talking with him I always have to remind him I want street performance and quick response. We haven't got there yet.
I came into this thread because I have a set of LS2 heads we were thinking about porting and adding to my setup. I'm wanting to get a lower stall tighter converter and I don't want to lose my low rpm torque. I don't know. Very interested in this thread.

If you want responsiveness, port the throttle body and mill the heads. Compression will make more power then porting and you will notice the difference throughout the rpm range.

The original question was what heads are the best bank for the buck. I think he found them.
After market heads or stock LS2 ported heads from a well known shop are in the $1800-2800 range. You can get big heads which will make big power with the right cam, intake, exhaust, and cubic inch. When deciding on a head for an LS2 with a stock or mild cam, stock A6 trans, stock torque converter, stock intake, 2.53 gears, and headers, it is a good idea to stick with smaller port heads in my opinion. This will keep port velocity up which has better cylinder filling resulting in higher average power or "power under the curve".

I had a 1993 Vette, that i installed a Vortex blower-in 1995-worked good---I agree with your statement about power, Edlebrock has a nice blower out now for the C6----here's the issue----Cams, headers, etc will produce approx. 100 extra RWHP-----cost @ $5500---a blower will produce approx. 125 RWHP---cost---$9000 ----So there is a budget concern---$$$ no object--GO BLOWER !!! My 1st car a 1940 Ford, I installed Edlelbrock heads & 2 carbs---WOW !!---110 HP By the way guys---I'm 75 years old, retired from General Motors for over 18 years, my wife of 54 years said, I'm never going to grow up !! I like doing something to the Vette every year, gives me something to look forward to. In 1963 I ran a "63 --427 Ford--A Stock--best time---13.5 at 107 mph--Got beat every week by the 409 Chevy's--HA !!!-----John
