it has to do with getting the oil back into the sump.

actually, in the K series, if they are upright, the oil drains back better, as the drain is next to the sparl plugs on the drivers side. i have heard no solid reasons why they have a lean, but suggestions include.
-easier to access dizzy, spark plugs and oil filter.
-safer in accident as the passenger gets dested instead of the driver.
-weight distribution, more even with only driver.
-the intake port angle thing, it angles up in the head, but if the manifold angled upwards it'd go thru the bonnet with an aircleaner, so the engine is tilted?
fwiw, TOSCO sold kits for K motors to mount them upright. their reason to mount upright? more room for sidedraughts and extractors and also much faster oil drainage to the sump. (twin dellorto 40's  )
kits included:
engine mounts, sump, oil pump and pickup, manifold stay, intake and exhaust manifolds, and bellhousing from a K motor to T box that removed the 15-20 degree tilt, so engine and box were aligned straight.
the kits were a few thousand back in the early 70's
