So the 90 degree fitting goes on the forward facing port? << correct
The straight AN fitting goes on the 4th plug from the front, there are 5. This one is between cyls 5 and 6. Yes.
Use a 90* fitting on the front of the hose and a 2nd 90* fitting on the rear of the hose - make sure you align the fittings before making the crimps. Allow 1/2" slack in the hose. Routing will depend on your engine mounts.
