Ported 60cc 317 Heads 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 SOLD

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!
