Cleaning motor blocks

[Matthew Wilder <mwilder@top.monad.net>]

Hi,
So in between welding in rust holes and letting fiberglass dry I've
gotten the motor on my TR4a stripped down to the block. The motor shop
wants the bearings and any plugs out which I was planning on doing
anyways before boiling out the block, but there's a plug in the front of
the block where the oil gally hole was drilled through. Will boiling out
the block hurt this? Can I also have the head or the crank done?

Thanks,
