The Cometic .030" MLS head gasket for Honda CBR600F4 (1999–2006) is built with a 69mm bore to restore cylinder head sealing. Multi-layer steel construction pairs embossed AMP-coated outer layers with an uncoated stainless steel shim to permit thickness variation. That design requires less clamp load, reduces bore distortion and helps conform load distribution across the sealing area for durable sealing.
