Aluminum threaded holes are easily damaged with the constant changing of parts on race engines. B&B addresses the carburetor mounting holes on intakes with our carburetor studs. Our studs with bullet moses allow for easy alignment of gaskets, spacers, and carburetors and are less likely to damage your parts. Each stud is machined from high grade alloy steel and are finished in black oxide. Kits come complete with heat-treated nuts and washers.
