Anyone run an intake without heat crossover in winter?

Blocked heat crossover on my Edelbrock Performer. When it wasn't blocked the fuel would boil in the carb after shutoff no matter what I did to insulate the carb. Even a heat shield wouldn't do the trick. As soon as the crossover was blocked, problem solved. Today's gas sucks.

No issues at all here. I have a manual choke. Then again it never gets too cold in San Diego so take it for what it's worth...
