Either they do, or there is a service bulletin describing how they need to
be added for '72-3 Type 3s. I've seen late replacement heads that have the
boss there, where they can be drilled for the tubes to be pressed in to make
the ports. RIMCO once told me they could install the tubes there if I wanted
them.

(The port consists of a short steel tube pressed into the head casting. That
tube sticks out and the end of the rubber hose slides over it.)

This is the way I went with on mine last year.  My VW mechanists got a pair
of these heads new that Jim speaks of.  Then drilled the bosses out threaded
the holes and put brass nipples in them so the hoses would have a place to
connect. The heads after he had installed the nipples were around $450 for
the pair which blew my engine budget sky high.  One the plus side they are
brand new heads and each head has a threaded hole for the temp sensor.  May
use the extra hole for a cylinder head temp gage sensor later.
