I have an ls2 making 418whp. Fast 102, vengeance racing cam (no known specs), headers, exhaust. I come from German cars and am pretty knowledgeable about those cars but not these at all. I am ready to take the next step and put heads on my 06 V. I will install myself so only cost is parts. I am on a budget and willing to spare a few HP to save a few bucks. I considered a set of used ls6 heads and work them. Please give me some advice. And from what I read I should expect about 460ish whp after heads?

tune time did that on a customers car with there spec'd cam and a stock ls3 intake manifold and the car put down just over that ! my tuner said that car was an absolute beast! i say DO IT, really nice power all motor! actually pretty torquey for an N/A setup as well.

Send your heads to Advanced Induction, get this done http://www.advancedinduction.com/LSX...cGMLS2Head.php
I have a set sitting in my basement that went to AI. A good friend of mine owns a shop and tunes LS motors and it's where he sends all of his customer's heads. I saw too many cars picking up RWHP in the high 30's low 40's. I think 1 netted around 48 horsepower at the wheels, but had a pretty healthy compressing increase.

Personally if you already have a cam and fast 102 Id throw some aftermarket heads on like said Trickflow as cast 220s or AFRs if you can afford it. Stay away from Dart. You will see around 440 with ported ls6s though so thats not a bad option it just wouldnt be my preference.

If you do aftermarket heads you will be in the midd 2k range. Advance Induction quoted me $1100 with return shipping to do the 232cc port job on my stock ls2 heads. just to give you a quick price refrence.

Swap for an ls3 top end, get the heads from texas-speed and a new intake and sell what you have, you will most likely break under 2k doing that. And you dont have to worry about PTV clearance unless you have VVT your valves will never high five your pistons. Going rectangle will give you more then you thought of
