Barney, Bill, Chip, Lawrie, Skip, and all other racers and mechanic
freaks:
<<<snip>>>
my MGA lost oil pressure completely at about 7000 rpm because
the oil pump was cavitating.

Okay, that comment has me thinking, terrible thought that is.
Where does the excess oil from the relief valve go to? Into the sump or
back into the pump? On the B series engine where does it go? On the
XPAG engine where does it go?
Was the effect of raising the oil pressure on racing engines actually to
decrease the flow rate at high RPM's and therefore reduce the oil
cavitation problem in the pump? This question of course depends on
where the excess oil from the pressure relief valve goes.
