I have engine serial number 42536 and it has a closedcrankcase ventilation system. The fuel pumpmounting, cast into the block, has a threaded hole (open into the crankcase)for the earlier ventilation system stud. In the laterclosed ventilation system, what is inthishole to seal it, a stud (as for the early system) or a bolt?
My block has a stud in it sticking out some 9/16'. I am pretty sure mine is a later, closed circuit breather engine (going by the tappet chaest cover anyway)
That stud was used to hold the lower half of a breather pipe that was as you saydiscontinued fairly early on in production. The stud however remained for a good few years.

Hi Andrew,
I forgot to mention my block had a never-used stud in it too and I am checking to see if that is correct. It looks as if it might be!
