Street Demon vs AVS2

With the 1/2" thick carb gasket recommended by edelbrock, the heat soak on my '70 340 is non-existent. The original AVS had a problem with it with the standard gasket, but the AVS-2 with the thicker one has cured the problem. I was drawn to the AVS-2 because of the annular discharge secondaries, and haven't been disappointed.
Years ago I was a big fan of the Holley double pumpers, but now I'm not sure I'll ever buy anything but an AVS-2 unless I'm building an engine just for racing.
