The maximum allowable free length is measured from the bottom of the flange to the end of the capscrew (Dimen- sion X). Part No. Maximum Free Length 3045849 74.5 mm [2.933 in] 3045850 139.5 mm [5.492 in] Installation A plastic insert is installed in all fuel inlet passages on new and ReCon W cylinder heads. NOTE: The fuel inlet passages are the lower row of drillings. Dependent upon the fuel plumbing option, one fuel inlet passage insert must be removed to allow fuel flow to the injectors.
If the insert is not removed, the engine will not start. Remove the pipe plug and use a sharp object to pull the insert from the hole. Caution: Do not drop the cylinder head on the cylinder head gasket. The gasket material can be damaged. Use a new gasket and install the cylinder head. Use clean 15W-40 oil to lightly coat the cylinder head capscrew threads and bottom of the flange. Allow the excess oil to drain from the capscrew threads.
