Welding to seal the extra vents is not a good idea. You can warp the block deck surface. Just because the machine ship went only "down to deck height" does not mean the "wavy" warped deck doesn't still have some low spots that can mean a future blown head gasket.

JB weld or quicksteel works fine. JB Weld will ooze more, so I installed it, taped over it and rotated the engine stand 180 degrees so that gravity worked with me, not against. I removed the tape and it was rock solid and has held up just fine.

If only that would work. Any hex plug large enough to seal the oil return holes would need to be drilled into the water jacket next to it = no worky. You could try to drill two small ones side by side into the rear edge of the block, but then you'd still need to lay some type of epoxy over them from the top side to seal it off.
