3. Remove cylinder head (B) and head gasket (C) from
the cylinder (D).
Cylinder Head Inspection
Thoroughly clean cylinder head surface to remove all
traces of gasket material and carbon.
CAUTION
Use care not to damage sealing surface.
Cylinder Head Warp
Lay a straight edge (A) across the surface of the cylinder
head (B) at several different points and measure warp by
inserting a feeler gauge between the straight edge and
the cylinder head surface. If warp exceeds the service
limit, replace the cylinder head.
Cylinder Head Warp Limit:

Valve Seal / Spring Service (On Engine)
NOTE: The following procedure is only for servicing
the top end of the valve train when replacing valve
springs or replacing valve seals.
In some cases the valve train can be serviced while the
cylinder head is still on the engine. Keep all parts in order
with respect to their location in the cylinder head.
WARNING
Wear eye protection or a face shield during cylinder
head disassembly and reassembly.
1. Having already removed the valve cover, rocker
arms and pushrods, align the cylinder to be worked
on at top dead center (TDC). Install the Valve
Pressure Hose (PU-45652) into the spark plug hole.
Hook the hose to an air compressor and supply 50 to
100 psi to the hose. This will seat the valves during
valve spring removal. Do not remove air supply until
reassembly is completed.
