These high quality Fabricated Aluminum Valve Covers are all hand TIG welded and finished with a nice polish. If you are looking for a custom look for your engine, look no further! The covers are finished with etching of "GTO" with the Pontiac Arrow. This is done with a machine that bonds the name to the cover under extreme heat that will not burn off, rub off, or peel. This is NOT A STICKER or DECAL! It becomes part of the cover! We can customize any cover with any name you want... Memorials, Race team name, engine builder, car name, etc... Email us for custom ideas! We also offer custom etched breather caps! *** Valve Covers comes with bolts, no gaskets. They measure approx 3" from bottom of flange to top of highest point of outside of cover, 2 1/4" at edge and 2 15/16" inside height which clears most roller rockers, but also recommend measuring before ordering to be sure on your application for clearance of rockers/intakes/alternator/Air Conditioner brackets... etc... Fits Pontiac 326-455
