Yes, cleaned all the sludge out.

Not to be beating a dead horse here, but your answer isn't clear (at least to me). Tanking engine parts is not the same thing as removing the plugs in the crank and cleaning the passages. Unless the person doing the engine cleaning is familiar with flatheads and flathead cranks this could be easily overlooked. And it can lead to problems after the engine is assembled.

OK, I was the one who misunderstood the question. I am not sure if the machine shop did this. This is the first time I have heard about this and I am somewhat concerned now.

Look at the sides of a crank throw (in line with the rod journal). You will see what looks like a small freeze plug. This should be obviously new-looking if they were removed and replaced after any accumulated gunk was cleaned out.

Just spoke to the person who worked on the motor and I am happy to say that they do remove the plugs to clean out the gunk.

Good to hear! That stuff dries and hardens, then the hot tank loosens it. If it's not cleaned out, it gets pumped right through the bearings!

Sounds good!
