The Cometic Super Sidewinder head and base gasket pairing for S&S 4 1/8 in applications combines a .027 head gasket with a .020 base gasket to provide balanced sealing with lower clamp‑load requirements. The construction is intended to distribute clamp force evenly, reduce bore distortion and avoid additional sealants or re‑torque. Cometic validates its gaskets through street and dyno testing for dependable results.
