Water proof Dist. & spark plug wires M38-A1

My M38A1 doesn't have the WP distributor or WP plug wires.

Would that mean it isn't equipped with the ventilation system for the crankcase, Trans, T/C, front and rear end, brakes, fuel tank and valve cover?

It does have the metal shields where the wiring connects.

Also, would there be a vacuum outlet for the distributor to cope with ionized gas?

Scratch the vacuum outlet because I will go to the WP distributor and it should have a vacuum outlet...right?

Thanks
