About This Product
These Cometic MLS cylinder head gaskets feature a 3-3/4" bore and .030" thickness, sold as a pair to seal both front and rear cylinders on one engine. Designed for 1999–2017 Twin Cam 88 and 96 models, they directly replace OEM 16775-99B. The multi-layer steel construction uses embossed stainless steel outer layers coated with high-temperature polymer rubber, eliminating the need for dowel pin o-rings while providing superior sealing and durability. Riveted outside the sealing surface for easier installation, these gaskets handle the heat and pressure of big twin motors better than stock composite units. When you're rebuilding top end, trust Cometic's proven MLS technology to keep combustion where it belongs.
Manufacturer part number: C9790.
