Intake Manifold Boots Aren't Cheap... Are they?

Were you using an electric impact or the hammer type?
The hammer type is an invaluable tool for these old bikes.

Basically the same as the chisel and hammer. When you hit it it engages gears in the device that turn the screw while the force from the hammer is directed inward and radially. Works like a champ.

Glad you were able to get them loose!

hammer type, I think the head was just too far gone from whatever yahoo was trying to get them off before me. Bolts are better anyways.

Agreed,
I use allen heads becuase they are pretty 8) (and they do the job)

I had the same problem with my intake boot screws, I did a little write up, the link is in my Sig for anyone else who stumbles across this. The hand impact driver will only work for the outer 2 bolts, you can however just remove the screw tip from the hand impact and rap on it with a hammer several times, then fit the correct size socket over the bit, press on the back of the ratchet while you turn and it should come out no problem. If they are really stubborn you can always use Penetrating oil and or heat (Propane<Map Gas<Oxy Acetylene).

If you strip them the best bet is cutting into a flat head using a well fitting screwdriver and apply pressure to the back of the screwdriver while turning, if you have a good screw driver it should have a wrench fitting on the shaft, and that helps a lot.

In addition to the other suggestions a pair of curved jaw vice grips like these work well for stripped screws if there is room to get them on.

Most impact drivers work with an extension

Do you fish the extension through the frame? The problem I had was the impact driver being too long and not having adequate clearance to swing a hammer to hit the impact driver.
