Why Proper Squish Clearance Matters

Squish clearance affects combustion efficiency, detonation resistance and engine performance. Clearance that is too tight can allow the piston to contact the cylinder head. Excessive clearance can reduce combustion efficiency and increase the risk of detonation.

The correct measurement depends on the engine, piston, connecting rod, operating RPM, fuel and intended use. Cylinder head machining should therefore be based on the complete engine combination rather than a universal specification.
