Bret,
You would be experiencing poor or fast idling characteristics when hot. Flat spots, and if you have vacuum gauge, a low reading that fluctuates at say 10 or 12 inches of vacuum. An engine that dies if you try to slow it down to normal idle. Now this assumes a stock motor with good initial timing at around 10 to 12 degrees BTDC.

A big cam can do some of the above.

I have heard of people spraying WD 40 or propane near the gasket area. If idle increases, when you do this, you may have an air leak there. Crap, you are near to me. Come on over on a sunny day!
