D Flatness of gasketed surface:
Using a straightedge and thickness gauge, check surface at 6
locations in total. If distortion limit, given below, is exceeded, cor-
rect gasketed surface with a surface plate and abrasive paper of
about #400 (Waterproof silicon carbide abrasive paper): place
paper on and over surface plate, and rub gasketed surface
against paper to grind off high spots. Should this fail to reduce
thickness gauge readings to within limit, replace cylinder head.
Leakage of combustion gases from this gasketed joint is often
due to warped gasketed surface: such leakage results in reduced
power output.
Limit of distortion: 0.05 mm (0.002 in.)
