I have to keep my eye out for detonation because I'm running 10:7 compression. I run the highest octane available which is 93 octane. The heads are 302s that have been cut down to 57cc combustion chambers. Whenever I take the heads off again I'm going to more than likely install larger exhaust valves and round off the sharp areas in the combustion chambers.

No it runs smooth and stays in the 180* range.
