Cylinder Head Specifications On
GM 1.6L Engines
General Motors suggests the following specifications be observed
when remanufacturing the cylinder head on 1.6L engines used in
Pontiac LeMans automobiles.
Measure the cylinder head height from the deck surface to the
rocker cover rail. The overall height should measure no less
than 3.770 (95.7mm). GM does not recommend the reuse of heads
that fall below this minimum specification.
The installed valve stem height should be measured using tool
#J25289. The tool straddles the valve and stem height is
measured from the tip of the valve stem to the tool. A minimum
clearance of .015 is recommended. The valve tip should never
extend beyond the gauge.
AERA machine shops have determined the actual installed valve
stem height to be 1.500 for the intake and 1.625 for the
exhaust valve when measured from the valve spring seat to the tip
of the valve.
