Overview

Briggs & Stratton 84001918 is the genuine #1 cylinder head assembly for Briggs & Stratton twin-cylinder (V-twin) overhead-valve engines, the Intek twins among them. It supersedes the earlier head 796231, and its partner for the other side of the engine is the #2 head 84001919. Replace it when the head is warped, cracked or has damaged valve seats or threads, or after a failed head gasket has damaged the sealing surface.
