As a general rule of thumb, you want every fitting, bolt, plug, etc
removed from the block prior to cleaning. Invariably, leaving them in
prevents the cleaning of some critical passage that was also invariably
plugged up with sludge and grime.
The plugs you are describing sound like drilling openings that are later
blinded with a threaded fitting. Threaded plugs are not pressed in btw,
they are rotated in. It is less critical to remove these, but it still
aids greatly in the cleaning process if you do remove them.
Drilling the center oil galley is covered in detail in the 1500
competition manual. If you do not have this manual, I would suggest you
procure a copy (readily available from the usual vendors). Not only
will it detail drilling the oil passages, but it will explain using the
MGB bearings instead of the Triumph bearings (very worthwhile).
