It's not the wheel notch.  It's the oil hole on the lifter itself
that pops up far enough that it would bleed oil out the top of lifter
bore.  The OEM lifters worked fine in a different 351C block and the
bore is tall enough, but in this engine, there's a big chamfer that
lets the oil bleed out.  The Crane lifters fixed the problem as they
have hole lower on the body.  We're also running hydraulic roller
lifters.  I've seen some hydraulic rollers with shrouded bodies but
they were very expensive.
