Boiling gas in the float bowls?

I had a worse problem, once hot and sat for a while, you'd start the car and gas would dribble out the bowl vents and kill the engine. I have a holley insulating kit installed now, but mostly you need to mix some race gas in with winter gas. A couple of gallons of 100 octane per tank seems to do it for me. I don't have the problem in the summer.

Here is a picture, you can see the heat shield under the carburetor.
