Do NOT run this engine until you change the valve springs to match the camshaft. Those springs are NOT near enough for your fast ramp XE lobe cam. You'll need 120-130lbs on the seat I would guess. Your cam sheet should have the recommended springs and installed height.

Once you do that I would start around 34* total timing. Im not a carb person so I don't know what to suggest for that.
