Subject: CHT Problem - Any Ideas

I have been having issues with my #3 cylinder running hotter that the rest of the cylinders when in the "racing" mode. 
 
Whenever I lean the engine for best power .... #3 gets into the 400 - 425 degree range ... I have to enrichen the mixture to get it to cool below 400, therefore losing max power .... I have replaced #3 cylinder but still have the same issue???
 
Before, I have had just regular baffling (it was good and tight as baffling goes), but just finished the tightest plenum with special attention to cooling deflectors for #3 cylinder.
 
Any ideas on what could be causing this problem and or a fix.  Getting ready to race Reno and this was a problem last year.  Takeoff, Cruise and LOP operations is OK?????
 
Standard IO 550N with 10 to 1 pistons - gami injectors????
 
Thanks for any help ....
