Insulating Against Heat on the Carb

The factory paper style insulators that are about 5/16 thick with brass eyelets in the bolt holes to help keep you from breaking the ears off the carb work pretty well and are or were until recently easy to get at most parts stores. Pretty much any big block Mopar with a Carter or Holley non spread bore 4 barrel from the late 60s to early 70s had one. I never use anything other than a 1/4" ratchet or short end wrench to bolt on a carb. DO NOT OVER TIGHTEN. If I had the room I would go with the largest 4 hole spacer I could get in phenolic.
