Those TIT and EGT figures, as well as CHT figures, were the same on my '73 P337. My oil temps were about 30 degrees higher during this time of year. Are you sure your vernitherm is working correctly? In the middle of winter I used to have oil temps as cool as yours, and my mechanic put duct tape (I mean a kit from Cessna, sorry) on my oil cooler to solve it. I never understood that, because I thought the vernitherm would be closed anyway. But I am not a mechanic...
