Revving the engine till you get valve-bounce is known as an Italian or Asian
tuneup depending on where in the world you live. It isn't ideal, or
recommended, but on a relatively 'safe' engine like the MGB the revs should
automatically be limited by the valve-bounce before any real harm is done.
But I can't see how that alone would have blown a core/freeze plug. I hope
it is an 'easy' one and not the one at the rear, but even that can be
replaced using a bolt and nut welded to a plate and some bracketry on the
back of the engine without having to pull it.
