PRC LS6 Stage 2.5 CNC Ported Heads WITH Cometic Head Gaskets
When I bought them they where $1800. Pricing has since be lowered. I had these heads slightly milled just to obtain a smooth finish needed to work with a cometic head gasket. I'm also including a brand new set of $160 cometic head gaskets with the heads. So I think my asking price is fairly reasonable.

The chambers are 62cc's. Stock the heads are 63-64cc's so Im not sure how much material was taken off but it was not much. Head gaskets are .040 thick cometics, they are 3.945 bore and are meant for a stock or 3.905 bore. On a stock ls1 the compression would be around 10.7 vs the 10.0 it is stock.
