83mm MLS Head Gasket .030 - Honda

The 83mm MLS Head Gasket .030 from Cometic Gaskets is a precision-engineered multi-layer steel cylinder head gasket engineered for Honda B-Series engines. Whether you're rebuilding a stock engine or maximizing power output on a modified platform, this gasket delivers the dependable sealing performance required to maintain compression integrity and prevent coolant or oil seepage. Head gaskets are critical wear items that deteriorate under thermal cycling, making OEM-specification replacements essential during any engine overhaul or cylinder head service.

Cometic's multi-layer steel (MLS) construction provides superior durability compared to conventional gaskets, with each layer engineered to compress and seal under high combustion pressures while resisting blow-by. The .030-inch compression thickness is precisely calculated for Honda B-Series applications to maintain proper deck height and combustion chamber volume—critical variables that affect compression ratio, ignition timing, and overall engine behavior. The 83mm bore diameter accommodates the full cylinder capacity, ensuring complete sealing across the gasket face while maintaining OEM clearance specifications around water passages and oil galleries.

This gasket is ideal for engine builders, restoration shops, and enthusiasts performing head gasket replacement on B16, B18, or B20 platforms. Installation requires proper torque sequence and head bolt tension to distribute clamping force evenly and achieve consistent compression across all cylinders. The lightweight 0.6-pound design facilitates handling during assembly, and the compact 8.2 x 17.4-inch footprint fits standard engine bay configurations without modification or clearance issues.
