CAUTION:
The cylinder head gasket surfaces are ground to a precision finish. Do not rest cylinder heads on gasket surfaces. Do not use any abrasive materials during cleaning of the surfaces. Hairline scratches, small burrs or dirt can provide a leak path for a cylinder head gasket. If gasket material remains on the sealing surface, use only a plastic-tipped scraper to remove the material. Do not attempt to reuse the head gaskets.
CAUTION:
Cylinder head bolts are torque-to-yield and cannot be reused.
NOTE:
The LH and RH cylinder head gaskets are not interchangeable.
NOTE:
Be sure camshaft bearing caps are installed in their original positions.
CAUTION:
Do not install the camshaft journal thrust caps until all of the camshaft bearing caps have been installed, or damage to the thrust caps can occur.
NOTE:
If new camshafts were installed, refer to VALVE CLEARANCE ADJUSTMENT in this article
.
CAUTION:
