That's good! Your head gaskets are probably OK then. Really, those temps are about normal. The oil does get hotter than the coolant. You might check the timing, if it is too slow it can raise EGTs which can make things quite hot under the hood. After that you might check for exhaust restriction e.g. plugged cat.
