Paul, it appears that the upper housing is the home made port?

 > 1. Is the housing (top one) naturally partitioned in this position of

the

PP or have you shaped the partition with Devcon.

That is a stock partition (web) along the top of the port location, that may
be in slightly different locations from year to year. The case bolt holes (if
present are all in the same location, so you can mix parts from different
years and get away with it.

 2. What is the hole in the outer cover - is that a guide hole ?

That is a core support hole that on some housings is opened to supply hot
water to the stock intake manifold. On some years the land area is there but
there is no hole.

 3. Does closing-off the water jacket (in this spot) cause any problems.

None at all. The factory periphery port housing is also solid in that same
location.

 3. What is that plug shaped section on the RHS - it looks like a bolt hole
for something.

That is a well for a stud that is used to hold the intake manifold on. That
area would be removed before installing the port liner (exhaust pipe tubing).

      George (down under)

      From what I remember of those pictures, it looked as though he had
built up a land area out of some material for a sealing surface. If that
material had been Devcon
Plastic Steel he could have drilled through it and the outer surface of the
housing and
tapped the whole thing of studs. But I don't know.
