The Cometic Twin Cam head and base gasket set supplies gaskets sized for a 4.250‑inch bore application and is designed to require less clamp load while conforming load distribution. The result is reduced bore distortion and a sealing solution that does not call for extra sealants or re-torquing, suitable for controlled engine rebuilds that prioritize consistent sealing.
