Carb Studs or Carb Bolts?

Always use studs in anything aluminum... It’s wise to replace factory oem transmission pan bolts with studs for the same exact reason. Over years of maintaining a carb, transmission, etc. You can avoid ruining an intake or transmission by using studs.

Agree 100%. I have cross threaded trans bolt pans more times than I care to admit, and I pulled all the threads out of a C4 pan hole while mounting a B&M shifter cable bracket. Ended up putting a long bolt and nut in it from the top and it always leaked.
