Torque Specifications

Cylinder Head Inspection
Measurement should be performed at a temperature of 20° C (68° F)
Using a precision straightedge and a feeler gauge, measure surfaces that contact the cylinder block for warpage

Maximum warpage 0.035 mm (0.00138 in.)
Allowable minimum cylinder head height 98.4 mm (3.874 in.)
Standard cylinder head height 98.5 mm (3.878 in.)
If warpage is more than maximum, correct the surface by grinding it or replace cylinder head
