  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).

  Steve, ???? Healey green for the normal intake manifold, begs the question, 
what color the Lemans intake manifolds on Lemans conversions of the 100? Mike

believe the intake manifolds left the factory painted the same Healey Green as 
the engine.? In any event, I painted mine with the Moss spray can engine paint 
in 1999 and it's still fine.? The intake manifold doesn't get that hot.? The 
key to any paint durability is how clean the surface is when you paint it.  ?

 Subject: [Healeys] Intake manifold finishes    ? I?m interested in my options 
for finishing my intake manifold.? It was powder coated clear 12 years ago, and 
the coating has yellowed at the head flanges from heat, and over the years  
what look like rust spots have developed in the powder coat, which is odd since 
the manifold is cast aluminum (see the attached photo).  ? I?d prefer to 
preserve the natural cast aluminum color, and I?m not a big fan of the chrome 
or polished look on the intake (my apologies to all you out there with nice 
shiny intake manifolds?it?s just not my taste).? I had the exhaust manifold 
Jet-Hot coated in a cast iron gray 12 years ago, and they still look great.? 
So, Jet-Hot coating the intake is one option, but the color samples they sent 
me of their lightest grays are all at best a medium gray; all considerably 
darker than their online color catalogue indicates.? I?m going to call them 
Monday, but I?m not sure they have a coating light enough.  ? I also don?t want 
to paint it, as I know that won?t hold up long term.? I?m curious about 
blasting the clear powder coat off and leaving the manifold uncoated.? How does 
the ?naked? aluminum hold up to the heat?? What have others done?? Your 
experience is appreciated.  ? Bruce Steele Brea, CA 1960 BN7  ?
