Best heads for Torquer v2?
Best heads for Torquer v2? Im in the market for a new set of heads and was wondering what would be an ideal choice with my cam.I was looking at tsp's PRC ported LS6 heads being that they are so cheap,but the darts seem appealing.What would you guys do,any help is appreciated.im looking for around 440rwhp.

I think Livernois make a really good set of heads for the money. If you think about buying these heads i recommend just buying the Stage 1 heads, because the only difference between Stage 1 and Stage 2 is the valve spring. oddly enough they both come with single coil springs. If the Torquer V2 camshaft requires the duals. I think you should look into the upgraded valve spring w/Manley TI retainer and spring cups. These spring are rated up to .670" max lift. If my memory serves me correct i think they cost 1,425 + freight. Not bad for a good quality piece.
Trickflow 215's are the best head for stock cubed motors, but I'd only get those if you're rebuilding the bottom end to handle 7000+. After that, I'd look at the Terminator heads from Texas Speed. Those flow slightly more than AFR 205's and have slightly smaller ports (200) for great low end and midrange.

I have a Torquer V2 and the TSP LS6 Stage 1 heads...car put down 420 and 390lb/ft on a stingy Super Flow dyno...Dynoject would be closer to 430/440. Car runs good, heads were cheap...cant lose!
btw I opted for the dual springs and valve job upgrade also...

IIRC someone used a livernois stage 1 head, stage 1 cam and did about the same number as you with less cam. Livernois builds some top level stuff, and I dont think their price vs. hp gained can be beat.

From everything i've seen the tfs heads make great power well below 7000.

Cam lobes are so aggressive for LSX engines, that with enough spring, just about any aftermarket cylinder head will breathe past 7000, even on a smaller cam. With so many out there running stock shortblocks, we're not used to seeing 7000-7500 shiftpoints. Keep in mind that guys running blueprinted GEN I or II are turning well past 7000 with heads that flow only a little better than a stock LS6 head. They're just using their 23 degree heads to their max potential.
I realize I may be in the minority here, but my main point is that on a stock shortblock, bigger is not always better.

Case in point: notice how long the powerband plateaus or "hangs on", as Tony Mamo puts, it past the hp peak on any ordinary h/c setup. On the average cammed motor that peaks at 6400, that motor is still making nearly max hp all the way to 7000. You could take that engine to 7000 or slightly past that and run faster because you'd never fall out of the heart of engines peak power.

I think im pretty much set on the TSP ported LS6 heads,id love to get the trickflows...but you just cant beat the price and performance of the tsp heads.I already have the prc dual spring on now,but i was maybe thinking of just getting the heads assembled with the duals,then selling the 241's with the springs....what do you guys think?
im sure it will make good power but u wont be optimise it without flycutting. ur going to leave a lot on the table imo. id keep ur stock heads too incase u ever sell the car.

And also don't be afraid to flycut it is an easy process for a decent shop.
