what the best way to block off the heat crossover on the intake of a 340 ?
 
Seems like they make special gaskets for that purpose. Google it.
If you do that with a stock mechanical choke the choke won’t work anymore.
 
Gas boiling/ vapor lock
yep
nice talking to you @ Carlisle !!!!!!!!

next project(S)
install
rebuilt avs carb with factory intake with a"cool carb" set up and a electronic converted prestolite dizzy
 
Ms900411 you need two of them they just leave a little pin hole for some heat, but that's for a 318 small ports. It comes with three gaskets one is almost completely blocked off you need two off the sets to make one set.
