Carb Studs or Carb Bolts?

I have bought a lot of old Edelbrock manifolds. (LD4B and D4B's) If everybody used studs the carb and thermostat threads wouldn't be all stripped out. I recommend studs for any aluminum fastening unless it has steel inserts.

I just put heli-coils in everything aluminum when they are new. You'll note that Edelbrock, for one, puts heli-coils in all the threads in their aluminum heads. Working in the aircraft industry, I have noted that most threaded holes get heli-coils installed at the OEM (brand-new parts).
