• Installing a COMETIC MLS (Multi Layer Steel) Head Gasket - The first thing you must do before installing the gasket, check all associated hardware thoroughly for nicks, scratches, or damaged threads as well as checking all threaded holes. If the hardware is inadequate or damaged, gasket failure may be eminent. Also change all the bolts and tap all threaded holes with the appropriate thread chase or cleaning tap. All hardware and mating surfaces should be free from any old sealers, rust, or carbon.
  Check your dowel pins as they register the gasket and head into proper location. Replace worn or damaged dowels. The gasket mating surfaces must be smooth 50RA or finer. Additional sealer is not required with Cometic MLS Head Gaskets. The outer layers of the gasket are coated with a .001" thick coating of viton (a high temperature flouroelastomer).
  Check brass rivet location to ensure the brass river does not interfere with the sealing surface on both the block and head. If the brass rivet needs to be removed a pair of side cutters will give the best results. Remove only the brass rivet.
  Once the gasket is in position double check all passages and overall fitment paying special attention to the bore and chamfer. The gasket should not fall in the bore or lay on the chamfer area. A gasket lying on the chamfer or in the bore will most likely cause a hot spot and lead to pre-ignition, possibly causing severe engine damage or gasket failure.

• Head Gasket Torque Procedure - If you are using studs or head bolts, torque hardware to the manufacturers specification. Fasteners works like a springs and must have proper Torque or Stretch applied to carry the correct amount of clamp force. Also use the proper lube or thread sealer for the job. All fasteners must be final torqued before thread sealant cures to achieve proper torque.
  Torque the fasteners in the correct sequence. It is critical to follow manufacturers torque sequence to apply clamp force evenly. A smooth continuous motion is important for every torque sequence. Re-torque is not necessary unless using hardware that has not been heat cycled.
