Looking at the photo of the cylinder head combustion chambers, I can't see the imprint of the metal ring of the head gasket well between #2 and #3 cylinders. I would guess the head is a bit warped and the head gasket is not sealing well in that area. Also looks like you are using the low riser Printoseal intake gaskets instead of the medium riser gaskets for the Edelbrock heads.
