If this is a fresh motor then it could very well run hot for a while. My 440 did but now it seems fine. Timing 15 deg initial and 36-38 total is a safe bet. Having approx 8-10 deg of vacuum advance off the ported carb port should be fine too. A rich mixture will produce higher exhaust gas temps so you may have carb issues. I'm guessing you don't know what the compression is but doing a cranking compression test will give some sort of an idea on what's going on.
