I'm reading old post here. I just sealed up my timing cover and oil pan. Now I'm reading the front plug needs a .040 hole in it to lube the timing. When I took the old ones out I did not see this. Also I thought these were npt I chased them with a npt tap and installed npt plugs. Now I'm reading these are straight thread. the rear plug is the factory straight thread. I did put the rear plug in for the distributor with a .040 hole in it.

Fronts are straight cut threads and the rears are a national pipe thread (NPT)
The 19/32 is for the back of the black and covers the hole that allows access to the pipe plug with the .040 hole that squirts oil on the distributor gear.

29/32" is for the back of the block that covers the pipe plug that squirts the distributor. The 19/32" and 15/16" can get thrown away.
