If this is really a drainback problem, it is so sever that neither of those
things would make a big enough difference. It is considered a mark of
quality if the inside of a cast iron engine block or gearcase is painted.
The reason is to seal the surface to prevent any casting sand or iron
particles from escaping into the oil, and to brevent buildup of cantaminants
on the surface. The solution here would be to open up the clearance holes in
the head around the pushrods to allow quicker drain from the valve cover.
Damn good idea regardless.
