Electronic ignition and a cartridge oil filter would be a good place to start. The only way for oil to get back into the crankcase from the timing case is through a hole that is level with the intermediate timing gear pinion. you could consider drilling a 1/4" hole to the left of the oil pump. This will prevent a good chunk of your oil hiding in the timing cover. Are your points in the timing cover or behind the barrels? A reed type breather valve in the old blanking plate behind the barrels would be a good move but you would need to look at some other holes into the main crankcase to facilitate the transfer of pressure.
