3500 and 3500B Family AllEngine News SEBD9328, December 2003, "New Cylinder Head Groups and Valve Mechanisms". Disregard this article. Corrections have been made to the supplement. The correct information follows.Description of Change: New cylinder head groups and assemblies are available for all 3500 and 3500B Engines. The new head groups and assemblies include a new exhaust valve with a larger stem diameter and an exhaust valve guide with a larger inside diameter. The larger stem diameter reduces stress in the valve stem during severe engine operation. The new groups also include floating valve bridges that eliminate the need for bridge adjustments. The new groups also include the following new components: valve springs, rotators, spring washers and valve stem seals.Adaptable To: Use the new basic cylinder head groups for Top End overhauls and for Major overhauls on all 3500 and 3500B Engines. The new basic cylinder head groups may be used individually in replacement of the former basic cylinder head groups.The former cylinder head groups and the new cylinder head groups are listed in Table 1.
