Manifold seals to the block around the insert. There is a gap between
the two on both sides of the port that functions as an air injection
point (emissions stuff).

Have any of you taken off the exhaust
mainfold. I was curious how
Mazda cast their manifold. The exhaust ports
have that insert in them, but
the gasket seals to the block. My question
is, is the manifold opening the
size of the gasket, or the size of the
insert? There is 3/16 to a 1/4 inch
(just guessing as I am not at the
hanger to measure) of insert inside the
exhaust port that will make a big
difference in how big to make the prts
on my flange, and ultimately how big
the exhaust runners are.
Ed Klepis is going to cut me an
intake and exhaust flange, and given
the quality of the rest of his stuff,
I anticipate it being very nice as
well. At any rate, he is going to
machine them, so I would assume he would
or could make several of them, so
If any of you are in need. Contact him,
I am sure he would be happy to
help.
