Cometic StreetPro Chrysler 420A/ECC top-end gasket kit for an 87.5mm bore with a .051" MLS cylinder head gasket. The MLS construction combines AMP-coated embossed outer layers with an adjustable uncoated stainless shim to suit thickness needs. Outer layers adapt to surface finishes and load conditions, requiring less clamp load, distributing sealing pressure and helping to control bore distortion for reliable sealing.
