Could someone please take a good 90 deg. Side shot of the cooling chamber
 that the port passes through of their finished P-ported housing? Both sides
 please, medium res like 1920x1080 there abouts???
 Thanks in advance.

 I don't have anything quite that high rez how about these?

 What are you looking for? I have some others that may focus on what you are
 interested in.

 I was hoping for a view with the tube installed (and perpendicular to the
 tube axis), to determine if there was a water passage through that chamber.
 Looking for possible differences in the cooling (and coolant flow patterns)
 of potted and un-pottted P-Port housings.

I'll take some better pictures tomorrow. Yes there are some water passages
around the welded tube version unlike the bonded in version. I am not sure if
its good or bad. I can come up with a few scenarios however. The tubes run ice
cold almost when the engine is running due to the evaporation of the fuel inside
the runner. That may cool off the water and heat the charge. Is that good? It
may result in less power and a more banana shaped engine. On the other hand it
might promote evaporation of the fuel and slightly decrease the BSFC (fuel
burn). Lycomings pass the intake runners through the oil pan for that reason. My
guess is it won't make a heck of a lot of difference either way for our purposes
but for car racing it might be measurable.

Here are a couple of shots I took today.
