My big issue with this van setup is with limited space between the engine cover and carb/air cleaner with the Action + intake I have at the moment, I have about a 1/4" extra room, gaskets included for anything, but the carb is sitting close to the intake either way. I've got an Air Gap and an M1 to play with, I was planning on running come next spring (along with other things planned) but I may just go ahead and slap it on, might help with the heat issue. Another option as well was running thin solid engine mounts to drop the engine a bit, but I've had to fabricate all the other stuff for it as it is now, and then it all will not align etc. It never ends
