Default 12 degree LS3 Head

What is the advantage to the diff valve angle? How is this going to improve the head? What kind of affect will this have on cam selection? Looks like nice head and is cheap right on par with factory CNC'd heads. Im excited!! lol

My bad too, that price is for each head. I don't see the demand for these heads being very high, when you could buy other aftermarket ls1 style heads that actually have a good aftermarket intake for them.
