Intake
Bill, you are correct that those are for manifold vacuum line. A
stock gasket won't cover them it has holes to allow the signal to pass into
the manifold where they are combined into one.
It makes a very nice and easy connection for your MAP sensor. It is
in the perfect place (as close to the intake as possible) and combines the 2
halves (as Tracy recommends you do)
I use it as my primary MAP sensor signal. I have another one at the
throttle body as the secondary. Both work fine in flight but the
primary seems to give a better idle.

While working on the plane yesterday, I pulled
some of the tape off the intake manifold area and discovered two little
holes in the primary injector area, on either side of the bolt hole. They go
into the primary injector area, and there are matching holes on the stock
manifold, that look like they are connected to a manifold vacuum line.
Question: Has anyone used these -- or did you
just block them off with the manifold gasket. I speculate that they are used
to help give a puff of air on the injection cycle.
