My Legacy racing stacks adapted to the LIV do not have  enough straight run for a heat muff, so I pick up warm air from directly below the no. 2 cylinder head.  I have a baffle which separates this flow from any potential exhaust leaks at the exhaust gasket.  Not desirable, but the only way I could get some heat in the cabin.  This system uses the pressure below the engine to drive the air into the cabin, and works well when the cowl flaps are closed, just like my old 182.

 

I will include pictures when I publish the document I am assembling.

Fred,

 

One of the big cowl leaks is the duct to Cabin Heat, what did you do there?
