I understand that you're moving to the MS System. That's okay, I 
don't know anything about it, so you clearly know more about it than 
I do. You may not need the AAR, if the MS system has a different way 
to handle the engine idle speed vs. warmup problem.

The breather is another matter. The ports on the heads are for clean 
air to go INTO the engine. If you breathe air out of those ports that 
will take care of the case getting pressurized, but at high rpm 
there's a LOT of oil spray in the rocker boxes, and if you draw your 
breather air from there you will get lots of oil in the process. It's 
really not what you want to do.

You need clean air to go into the heads and crankcase blowby to exit 
via the breather box (which serves as an oil mist separator.)
