ls6 and ls2 heads and intake ????

The LS1 intake will bolt up and work, but a LS6 intake would be better. Yes, the 317s have the same ports as the 243s. The problem with milling the 317s for more compression is that you would have to remove .045"- .050" just to have the same size chamber as the 243s. That would reduce your piston to valve clearance by quite a bit.
