This Cometic copper head gasket is for Chrysler LA V8 engines with a 4.200in bore and 0.043in thickness. Market notes indicate the copper construction requires less clamp load. The gasket features embossed outer layers, Viton coating, and is engineered to conform load distribution across the sealing area to minimize bore distortion without requiring sealants or re‑torque.
