Many of the parts you'd mentioned in your post are quite interchangeable through many years. They, in and of themselves can not identify a block.
I might suggest you buy my book. It has a very thorough description as well as many detailed photos to aid you in your quest.

The 85 horsepower engine was available in both the DeLuxe and Ford V-8 models.
All blocks were cast iron. Some identifying characteristics are as follows:
The top water openings, between the center cylinders, were shaped like triangles while the center and bottom openings were shaped like trapezoids.
The top surface that mated with the valve chamber cover was smooth. That is, there was no raised flange. Raised flanges did not appear until approximately the middle of August, 1940. They arrived too late for 1940 model inclusion.
The standard bore was 3 1/16" diameter. Some engines were sleeved while others were not.
Four core plugs were on the machined surface that mated with the oil pan. These plugs created raised areas on the sides of the block.
Exhaust manifold mating surfaces were raised about 5/16" from the casting proper. This is unlike later blocks which were nearly flush with the casting.
Main bearing journals were a nominal 2.5" diameter.
Crankshaft length was a nominal 26.03".
A definite “shelf’ was cast above the timing gear cover. To help identify a correct engine block, this shelf is often used for the “pencil test” — meaning that a pencil will easily rest on this shelf.
The top of clutch housing was integral of the block casting.

Engine blocks were painted what is commonly referred to as “Ford Engine Green”. The machined surface areas that mated with the cylinder heads and valve chamber cover were masked prior to painting. Thus, those areas were intended to remain free of paint.
Some blocks were stamp coded on the left of the top machined surface between the cylinder head and valve chamber cover, very near the front, to indicate various items used in production. On occasion these codes were stamped erroneously on the right side. Common codes were “HS” for hardened sleeves, “AP” for aluminum pistons.
Two drain cocks (48-8115) were installed in the engine block. Each was slightly below the exhaust manifold and directly behind the water pump / engine mount.
