Am currently replacing my 13B rotary in the 9A with O-320 and was about to drill the 4 EGT probes and have not put my hands on the instruction for how far down from the port to locate them. Also seems like before they were to be mounted in a straight section, but my new ones start bending after their flange almost immediately. Anyone with up to date info on best location??

Doesn't make a whole lot of difference, just make sure they  are all drilled equal distance from the 

 exhaust flange.  Mine are one inch from the  flange.

Your post beckons the question, Why abandon a rotary 13B for a horizontal four stroke O-320?

I would suggest that you contact Barrett, Aerosport, Performance or Mattituck on the correct distance from the flange.  It needs to be consistent, the depth of insertion is also a factor, the probe’s life is affected and I beg to differ that the distance is unimportant.  As you increase the distance from 2 to 4 inches the combustion impulse is reduced and the read becomes more consistent.  The temperature will drop as the distance increases (slightly), but what is important is the consistency of Max Temp for ROP or LOP operations.  

   

You can be assured that one inch will avoid the first tubing bend but placing it closer than the pros advise will hasten a replacement probe.  You may find a recommendation of at least 2” and not more than 4”.  Consult the professional engine builders.

The answer is in the post.  He is selling and  there is probably minimal 

 market for a rotary aircraft.

Burnie, 

Are you going to get the first RV 12 kit?  I haven't heard from my engine mount and gear legs.
