1937 with a 59AB engine, offenhauser manifold, sharp heads, denton headers, two stomberg 97 carbs. Has a mallory electronic distributor with the corresponding coil. It ran great before. Now it runs great until it gets hot and starts to miss and evolves into stalling with the foot off the gas. It STARTS immediately every time after it stalls, but resumes running with mega missing, until it stalls again. Any ideas? Ignition? But it starts every time after stalling, but misses bad. It recovers while missing if I pump the gas pedal like crazy but drops back into mega missing. Carbs? It starts and runs great until I am at temperature for a while (160-180). Coil? Resistor?
There is a strange sound coming out of the engine when this condition presents, like one side of the engine isn't firing the fuel, kind of a gurgling.

Brain stormers needed. Thanks guys.
