Cylinder Head Inspection for Warpage
  1. Check the cylinder head for warpage. Measure along the edges, and three ways across the center.
    • If warpage is less than 0.05 mm (0.002 in.) cylinder head resurfacing is not required.
    • If warpage is 0.05 mm (0.002 in.) or more, resurface the cylinder head within the standard range.
