I am swapping back to 317s for my blower and am putting these up for sale. They have been mildly hand ported by a local, reputable ls engine builder. They have also been milled .010" to clean up the surface etc. They came with the yellow springs, not sure if they have the sodium valves or not. Will be pulling on sunday. $500+shipping and paypal fees if thats what you are using.
Thanks,
Joe
