Oh, it's doable, trust me. I had my Solexes off twice in one day just prior to
Shasta to resolve water leaks from the head into the intake manifold (there's a
water passage through the intake manifold to allow hot water to warm up the
carbs and atomize the mixture better when the engine is just warming up). You
basically have to "embrace the manifolds" and pass an open-end wrench from hand
to hand to get it off. If you pull the carbs off the manifold first, you can get
to the two inner studs with a ratchet wrench, but the studs between #1 intake
and exhaust and #4 intake and exhaust are a real pain. And of course, the carbs
will then be out of balance.
It turned out that the cheapo header I'm using has the thin flange with tabs
welded on to get to the "correct" thickness to match the intake manifold, but
the Solex manifold is a little thinner than the SU one, so the thick washers
weren't making solid contact with the intake manifold. I ground about .050" off
the tabs and the leaks stopped. Some people grind a step on the backside of the
washers, but I wasn't sure I could keep the washers positioned while tightening,
so I cut down the tabs instead.

Subject: replacing intake exhaust gasket wth engine in car.
Hello All,
Well I was looking under the car and it looks like the water staining
the
block was not coming from the freeze plugs. It appears to be coming from up
higher. It appears to be coming from either the block head interface or
the intake exhaust gasket. Does the intake exhaust gasket seal water somehow?
I hope so cause then I will have to remove the head... How can I remove the
intake exhaust stuff with the engine in the car??
I don't really see any easy way to get at the lower exhaust header
bolts that are on the bottom and burried.
Thanks,
