  • Piston to head clearance
  • Does anyone know the piston to head clearance for a 8N 120ci engine? Thanks

  • Set the head in place without the head gasket and rotate the crankshaft, if it doesn't touch it is ok, if it does then grind away the inner surface of the head until it clears. Use Dykem on the combustion chamber to see where it hits.

    I think this procedure gives about 0.050" clearance.
