Default LS2 Heads???

I am currently building an iron 408 for my TA with a desent size cam(ms4, trex) and was wondering if LS2/LS6 heads would dissapoint me on power and torque. I am aiming for about 480ish rwhp and good power under the curve but i do not know if these heads would prevent that. All help appreciated

Ya I'd like to know too. On ebay there are CNCd LS2 heads matched to the LS2 intake with the 90mm throttle body assembled with stock valves and dual springs for like $1200!

I run LS2/LS6 heads and seem to be doing O.K , but remember you get what you pay for.

not to jack the thread but, damn $1200? is it a store or an auction?


i would immagine that that set up will get you at least close to your peak power goal, but you will certainly have great power and torque down low.

A properly ported LS6 head on a 408 with a Fast should be guaranteed 500+ RWHP through a stick.
480 RHWP through a LS6 intake is possible, we just had a set of our LS6 heads make 480 RWHP on a stock shortblock 5.7 through a locked A4...so you goals should be easy, but like was mentioned above, it's not cheap, about $1300 with you supplying the castings.
