In response to Rick Agente N360ZR cylinder temps. The 450 deg F cylinder
temp is too high.  The exit area for the engine cooling air must be larger
than the inlet area by about 1.2 to 1.5.  It sound like the engine is
simply not cooling enough.  Also the baffling around the engine must be
tight so that all the air passes around the cylinder  fins.  This is real
important and that may be your problem.  Good luck, Marty Hollmann
