[Healeys] Intake manifold finishes

[Bob Spidell]

The manifolds on our original 100M were bare Al, but I can't say whether 
they came that way or the paint burned off.  I suspect--since they added 
the larger carbs at the Healey factory--they wouldn't have bothered to 
paint them (since they usually couldn't be bothered to pull the engine 
to replace the cam).
