You may want to check your orientation on your exhaust heat riser valve, we are discussing this on another thread on CRG. I think one person said it looks like this in the AIM others had factory unrestored ones parallel with the frame rail, or maybe they were installed both ways?
Also I can't tell for sure but your spark plug boot shields should have a semi curve notch in them, I can't seem to see it on yours, but maybe they have them and your manifolds are to clean for me to tell from the pic.
