What radiator did you install? Spectra Premium has fixed hot running for some people.
If your t-stat is new, it should work fine, but it couldn't hurt to toss in another t-stat. They only cost $5.
The heater core circuit aids in continually exposing the t-stat to a significant volume of flowing engine coolant. This allows the t-stat to more rapidly sense the coolant temperature while the t-stat is still closed. If your heater core becomes clogged, your stat will not open until your engine gets hot enough to make the water in the vicinity of the t-stat higher than 195F. Other parts of the coolant in the motor may be much warmer by the time that happens.
