For what it's worth here is a photo of a block from the SM. To me it appears the studs were mostly threaded down to the end of the threads but doesn't look like they were concerned that much about all tops being the same height even coming from the factory.

From the parts manual, the length of the studs are given and the utility section has the specs for the washer and nut.

There was a change in the threads on the studs which could affect your engine. The article is specific in stating the two threads are not interchangeable and from personal experience I can attest that threading the rolled type stud into a block with the cut threads can be very difficult. If someone has mixed them in the past there could be some issues in getting the height down to approximately the end of the threaded section. If the studs won't go down far enough McMaster has some extra thick washers that might work better than standards.
