TonyG Posted February 17, 2007 Report Share Posted February 17, 2007 Stage 3 HPE Ported LS1 LS6 LS2 Race Heads! These heads were ported by the best in the country and have over $2400 invested in them. They have made more horsepower on a stock cubic inch LS1 we've ever seen for a stock casting. These heads make for killer horsepower on your normal heads/cam stock engined camaro/trans am or corvette and also will make huge power on any bigger stroker 383/402/408/427. Great for your daily driver or your race motor. Will work great with nitrous, blower and turbo applications. I have flowed these heads against many other companies best offerings on the market and these are better. Back to back vs AFR 205's, TEA Stg 3s and others have not made the same horsepower and torque #'s as I've seen from these. These heads were just fully gone through and inspected after being removed from approx 3000 miles of street use. They are in like new condition and need nothing. Ready to bolt on and go! They feature many high dollar upgrades including: -2.02/1.57 Ferrea stainless race valves -Double Race Springs are from Competition Products. 1.25" diameter, good to 650 lift. Springs were fully shot peened, micro polished and destressed. These springs were approx $400 alone. -Fully hand finished and flow tested -Chromemoly retainers and SLP seals -68 CC Combusion chambers Superflow Flow Sheet: Lift Int Exh 200 147 131 300 214 166 400 256 201 500 291 226 550 301 231 600 308 235 Asking $1300, I am losing out on over $1k!!
