What a deal!
GM part # 12480716 LS6 CNC Ported Cylinder Head
$906 each or $1812 for the pair.
That price includes valves and springs. Does anyone know how well these are ported and what type of flow they produce?

No, I was serious. Do you know the flow of a "properly" ported stage one LS1 head compared to these heads? This price is with no core and from what I've seen advertised it usually costs more than that and you have to give them your heads in exchange. So does anyone know the flow #'s on these heads?
