Question from a 337 shopper (hot rear engine)

[hewilson]

I'm new to aviation. Just began my IFR training but I'm anticipating getting a 337 when all my training is complete. I've heard mostly good things about the plane but two sources have said that the rear engine tends to run hot and this leads to increased maintenance and/or it does not make the full overhaul time. Is this correct and if so, have any after market solutions been worked out? Thanks in advance for any input.
