Trying for 45-50+ rwhp gain 5.3VsLS6 Heads+Intake and TB
Hey guys ive got a 2004 GTO with Mods and dyno numbers listed in sig and was looking to TRY and get 45 or so more rwhp. Im kinda on a budget and so far am stuck between the PRC Stg 2.5 5.3L heads and the Patriot Stg 2 LS6 heads for the money. kinda leaning toward milled 5.3's and crush head gasket to get close to 11:1 compression
I would also be adding a Throttle body (85mm minimum) and either porting my ls6 intake or going with a street warrior (if and when it comes out in feb). Sorry i can't afford AFR or Trick Flow but would love them! I was thinking i would try to get around 12 with an intake and throttle body and hoping for around 35 more from heads on top of that. What do you all think?

Don't bother with the 85mm TB. it's a waste. just go 90.

Those look nice and aren't as expensive as many.
John, i have a 2000 M6 T/A i'm looking at doing a very similar combo too.. Would love to come in close those numbers. my cam is a TSP torquer V2 not quite as agressive and a 112 LSA 232/234, .595"/.598" My question to you is What exhaust do you have.

Out of the box with just clean-up milling to ensure they are flat they are right at 62cc chambers.
$934.99+shipping for the Stage 2.5 5.3L heads with no spring kit. Milling would depend on what lobes that cam utilizes and what kind of advance you run.
