EMP 27-00655
Gasket, Cylinder Head
The EMP 27-00655 is made in Japan and is visually/technically indistinguishable from the Yamaha OEM gasket (same composite construction, fire rings, and passage geometry), indicating OEM-level sealing reliability for this high-consequence repair. It delivers that quality with the value advantage of an aftermarket-branded part.

Japan-made EMP gasket matches the OEM Yamaha profile, composite texture, and metallic fire rings, including the same rectangular coolant-passage geometry. Construction appears indistinguishable from OEM, strongly suggesting OEM-equivalent manufacturing and sealing performance.

Taiwan-made Peach Motors gasket is a very close reproduction, with clean die-cut edges and well-fitted metallic fire rings that closely resemble the OEM part. Fitment geometry appears to match well, but it does not have the confirmed Japanese OEM manufacturing/QC provenance.

Taiwan-made non-asbestos composite gasket with metallic fire rings and an added printed sealant bead around the perimeter and ports. The sealant track can help on imperfect used surfaces, but the overall design approach differs from the OEM Japanese gasket, indicating lower fidelity to the original.

Recmar’s gasket closely matches the OEM geometry (scalloped perimeter, bolt-hole pattern, and subdivided rectangular coolant passage) and uses metallic fire rings. However, being produced in China introduces more potential QC variability for a head-gasket application, so careful inspection before installation is important.
