These 317 heads have the same OEM ports as the LS6 heads with a larger 70cc Combustion chamber

I am selling them because I have decided to stop my performance modding on the Z at a full exhaust, so I just don't need these any longer


The Heads have been milled to 60cc, for a better N/A street performance setup, and the manifold surfaces have also been milled to compensate and allow the OEM manifold to fit, and they have had bronze valve guides installed.

I am looking for $450/BO + shipping which should run around $50

I'm not sure on the history of these heads but they do flow, I did at one point have the flow sheets for them but the sheets been misplaced.

The port work looks great, your basically buying P/P'ed 243's for less than half the price, and they've got bronze valves guides!

If only the chambers were a little bigger.

I really don't want to be 10.1:1 on a boosted motor. I am 9.2:1 now looking to go 9.6:1 with a 64 cc head

I didn't even see the sig, but your right, probably not the best head for a boosted motor.

Unfortunately i just don't have them any longer; if I did I'm sure they would have sold long ago for more than I'm asking now.
