Note: There are currently two types of cylinder head bolts that are being used. The first type is a full shank design that is shown in Illustration 2. The second type is a reduced shank design that is shown in Illustration 3.
Note: Lubricate the following areas with 6V-4876 Lubricant prior to assembly: bolt threads, underside of the bolt heads and washers.
