Product Description

The Skunk2 366-05-4000 MLS Head Gasket is engineered for high-performance Honda/Acura K-series VTEC engines (K20 and K24). With a robust multiple-layer steel construction, laser-welded layers, and a high-grade HR-180 fluoroelastomer coating, this gasket ensures superior sealing under conditions of high RPM, elevated cylinder pressures, and boosted/modified applications.

This gasket is designed to fit engines with up to 87.00 mm bore (3.425") and up to 1.35 mm overbore - making it ideal for bored or performance-built K-series blocks. The 0.053" (1.35 mm) thickness contributes to consistent compression ratio and head clearance management, which is especially important in track, turbo, or high-output builds.

Installation is fairly straightforward given correct block preparation, head surface finish, and torque procedures. As with all performance head gaskets, proper installation includes verifying bore size, head bolt torque patterns, surface flatness, and the use of quality hardware. This listing confirms fitment across the years and models listed above; verify your specific engine code and build conditions before purchase.
