317 is the cylinder head casting number. You can use an LS6 intake manifold with these heads. I was referring to the 317 cylinder heads being a similar port design to that of the LS6 cylinder head, which is why the 317 heads are a cheap 'bang for your buck' head used on many forced induction motors. They not only decrease compression due to their larger combustion chambers, they flow very well too for a factory GM casting.
