Lots of good ideas above! What plugs are you using and what gap? What type of ignition system? What plug wires? Put a vacuum gauge on the engine to determine if the vacuum is low You can also use it to monitor fuel pressure and adjust the idle mixture adjustment. (don't guess). What size power valves.....69??? My car runs lean on 42 had to use slightly larger mains. You can remove the PV and check the gaskets to make sure they are seating and the gaskets should be slightly deformed like your intake gasket. You should have a metal tube from the bottom of the fuel pump adapter to the engine block. Maybe you just don't show it in your photos. When installing new fuel input needles and seats it is good to gently tap the needle into the seat. This will form the seat to the needle and allow better fuel shut off.
