so what sort of hp/tq are you expecting from them? how much did they run? are you doing the install yourself? did you buy a cam from them too? what cam?

I'm typing, I'm typing :bang:

WOW :drool: Those are nice!!! If those were mine I would probley show them off for a month before I put them on my truck :devil:

As per their design:
"We've got a 6.0l CNC cylinder head assembly at an introductory price of $1300.00 per pair, exchanged. The heads are equipped with stainless valves (2.02"/1.57") dual springs and titanium retainers. The port flow is designed for engines with cams utilizing .575" lift or less. The exhaust port is designed for use in high load and/or boosted applications such as trucks."

I will be using these heads with a Comp Cams .581/.581 220/224 115LSA bumpstick :judge:
Expected power when complete 500rwhp/500rwtq :devil:

As quoted by Richard:
"We worked hard to get the mid lift flow as high as possible without sacraficing too much high lift flow. I feel this setup will work very well for aspirated and supercharged truck engines because they typically don't run large lift cams. The intake port flow peak occurs at .575" lift, while the exhaust is pretty much done by .500"
