Measuring Cylinder Head Thickness
Measure cylinder head thickness from rocker
cavity-to-combustion face.
If cylinder head thickness is less than wear limit, DO NOT
attempt to resurface. Install a new cylinder head.
If cylinder head thickness is greater than wear limit, a
MAXIMUM of 0.15 mm (0.006 in.) can be ground from
new part dimension for a minimum overall thickness. (See
RESURFACE CYLINDER HEAD COMBUSTION FACE,
later in this group.)
