Cylinder Heads

  1. Inspect the cylinder head for out-of-flatness, using a straightedge and a feeler gauge. If measurements exceed 0.0508 mm (0.002 in.) replace the cylinder head.
  2. Inspect the valve seats for damage. Service the valve seats as necessary.
  3. Inspect the valve guides for wear, cracks or looseness. If either condition exist, replace the cylinder head.
