Thickness & Notch Selection Guide
IMPORTANT: This gasket kit is available in multiple thickness variants. Using the wrong gasket can cause engine damage. The correct gasket is determined by measuring piston protrusion.
Notch Count Thickness Range Application
1-Notch 1.05mm / 1.30mm / 1.60mm For minimum piston protrusion
2-Notch 1.10mm / 1.35mm / 1.65mm For standard piston protrusion
3-Notch 1.15mm / 1.40mm / 1.70mm For maximum piston protrusion
How to Determine the Correct Gasket
  1. Check the notch count on your original gasket (1, 2, or 3 notches)
  2. The correct gasket thickness is determined by the piston projection from the cylinder block upper surface
  3. Always verify with the engine serial number for precise identification
