QuadrajetParts.com recommends that this inlet fitting thread installation kit be only used with a milling machine or other suitable tool that will allow secure fixturing of carburetor casting and indexing of tap to casting. Also note that 1"-20 Rochester Quadrajets seal at the bottom of the inlet fitting, requiring that the tap be modified for this specific application. We will supply you with instructions of how to modify the tap for this purpose.
