582 High EGT'S HELP

How does your exhaust look? Any leaks at the joints or gaskets? Any chance the can is partially plugged? Seems like an odd one. Really shouldn't have to move the needle position by more than one position from stock.

Carb socket health (lack of deterioration and health) is another good thing to look at.

Having one side behave differently than the other almost sounds like synchronization. Double check both slides are at the same position together. Both slide cutouts should reach the top edge of the throat at the same time

Are you confident in your engine RPM? Don't trust the original units they can be off quite a bit. If you haven't done it already toss a Tini Tach on it. Cheap and easy to install.

Other than that it might be an air leak somewhere or maybe a fuel delivery problem. Have you accomplished a compression check recently. If not might be worth a double check.

I pic of your install might help as well.
