Installation Instructions

Cometic MLS gaskets install just as an old obsolete composite material gasket.
Be sure the head and deck surfaces are machined to an adequate finish as detailed above.
We recommend using a couple of light coats of Permatex Coppercoat to ensure a good water seal.
If any water seepage should occur allow the engine to heat cycle a few times, most likely it will seal itself once the gaskets form to the head and deck.  If it continues to seep add a can of Justice Brothers Radiator Pepper Based Sealer Part # RSL/2 about $7.00 to the cooling system.
Tork to bolt manufacturers specifications, re-tork should not be required with aftermarket ARP bolts or studs if pre stretch instruction from the manufacturer are follwed..


ARP, Justice Bros., Permatex, Coppercoat are registered trade marks and used for reference purposes only and recommended by FBO based on personal experience working with this product.
