My thought is yes, I would keep the hose from the valve cover to the carb base. That is your PCV valve pathway to keep your crankcase fro becoming overpressurized. The design is that you have a vent path from the opposite valve cover (whether or not it connects to the air cleaner) to pull fresh air into the crankcase. This allows for sweeping gases out of the crankcase to the intake of the engine to be burned away. If you do not run a PCV setup, then you will have high pressure in the crankcase, which promotes oil leakage at gaskets and other connections. I run a line from my passenger side valve cover to the bottom of my open air cleaner and then a line from the PCV valve on the driver's side valve cover to my carb base. I do not have any leakage so far.

If you want to clean up the top side of the motor, then move everything else that is on top of it to a corner in the engine comartment and run a vacuum source from the back of the intake to that point. That way there is very little on top of the motor and it doesn't look cluttered.

Get those spark plug wires in wire looms down the side of the valve cover (just above the exhaust manifolds and seperate them so that they are neater and that will clean up the top a lot.
