I am currently distracted building a 445 FE stroker motor for my 65 Galaxie. Part of the build is upgrading the rocker assemblies. This includes end rocker stand supports and shaft spacers between the stands. The supports on the ends of each shaft add strength to the unsupported end of the shaft to prevent breakage often associated with high tension springs. The spacers with shims keep the rocker arm centered on the valve stem tip. The Y block rocker arm assembly design is the same as the FE but I haven't seen any aftermarket parts for the Y. Am I missing something?
