Why this part
Composite gaskets fail where MLS gaskets thrive — repeated heat cycles, high clamp loads, and aggressive cam timing all accelerate their demise. The Cometic MLS construction in this unit uses multiple embossed steel layers that spring back and reseal, making it the correct choice for any 265 Hemi running above stock power levels. The price reflects a part that won't need replacing mid-season.
