Pop out the oil galley plugs and the freeze plugs.

Hopefully during the last rebuild the oil galley plug below the Dizzy got removed, if not have the shop do that.

If it’s a recent rebuild that was likely hot tanked before then as long as the oil galley passages are clear then there’s no need to either hot tank the block or bake it as some shops do to clean it.

This will save you from the cost of replacing the cam bearings which should still be fine if the Cam comes out easy.

Just spray it down at home to remove oil with some brakecleen outside.

Have the shop open up the oil pump feed hole in the block some so they can grind a taper into that passage and the the pump side will then have a lip to block some reversion pressure that’s bad to have.

If the car is Auto. Look over the flexplate carefully for signs of beginning cracks.
This way you will not waste money on having to possibly get another one after the balance job.

Also look over the freeze plugs in the end of your heads.
If they do not have a size stamped on them then they are likely still the original ones.

If so then you want to replace those end ones at least because there almost nothing more aggravating then to have to yank a head because a original rear end plug has finally rotted out .
