Clean and inspect all hardware prior to installation, looking for shipping damages and defects. 4. Seal all threads extending into a water jacket with ARP thread sealer. Lubricate all threads on dry deck and/or main cap applications with ARP Ultra-Torque fastener assembly lubricant. 5. Following the engine manufacturer’s torque sequence, tighten the bolts to the recommended torque value found on the instructions provided with each kit . NOTE: All wet deck head bolt applications will require some type of sealant on the bolt threads to prevent coolant leakage. Always check each application (import and domestic) prior to installation to determine whether your application has a “wet deck” or “dry deck” cylinder block. 3. Install the head gasket and head, checking for improper fit, binding or misalignment. Make sure all mating surfaces are fully seated. Install the washers on the bolts with the chamfered side of the washer located towards the head of each bolt.
