drive in the rear end of the intake camshaft.
NOTEInstall new camshafts using the following procedure.
(1) Remove the rocker arms.
(2) Lay the camshafts on the cylinder head and install
the bearing caps.
(3) Check that the camshaft can be easily turned by
hand.(4) After checking, remove the bearing caps and the
camshafts, and install the rocker arms.
