	Before I wrote about that small diameter cross line that feeds
the mag drive, I thought about the internal oil feed in the engine and
believe the mains, rods and the cylinder head with the tappets and
rocker arm assembly all get theirs direct ahead of the filter somehow.
Could be wrong so I didn't mention that part of it. Whenever I've had
the valve cover off a B engine, there has always been lots of oil going
topside. I think the rods do some splash lubrication too.
