1963 Pontiac Tempest Performance Engines

COMP Cams offers a complete line of valve stem seals, from the umbrella seals to the positive-stop Teflon seal. These seals are a must to keep unwanted oil from entering the combustion chamber through the clearance in the valve guides. The umbrella seal is normally used when a larger-than-stock diameter spring is used, in the case of a double spring, the positive-stop Teflon seal is used. The umbrella seals require no machining, but with the Teflon seal it is necessary to disassemble the heads and machine the top of the guide with a special .530 diameter cutter. Whenever you are planning an engine overhaul or a cam change, don’t forget the valve seals.

Product Features:

• Work with .530″ guides and 11/32″ valve stem diameter
• Valve stem oil seals keep unwanted oil from entering the combustion chamber
• Several different types of valve seals are offered

Ultra-Seal is Mr. Gasket premium valve cover gasket material. It’s manufactured from a high density cork and rubber blend with a black latex coat applied to the outside to help seal minor flange irregularites and eliminate oil leakage. It creates a positive seal by controlled swelling of the gasket material when exposed to hot oil. For original equipment replacement, high performance street, drag race and oval track use. Sold as a pair, these gaskets are .187 inch thick.

Product Features:

• Manufactured from high-density cork /rubber blend gasket material
• A black latex rubber coating is applied to outside of gasket to help seal minor flange irregularities and eliminate the possibility of oil leakage
• Creates a positive seal by controlled swelling of the gasket material when exposed to hot engine oil
• For OE replacement, high performance street, drag race and oval track
• .187″ thick
• Handles Ex Flange Pressure
• Forms Leak Proof Seal
• Black Latex Coating

Mr. Gasket Performance Valve Cover Gaskets are high-density cork/rubber blend gaskets that use evenly sized cork particles distributed evenly throughout the rubber binder. The result is a compressible valve cover gasket without leak paths. These gaskets create a positive seal by controlled swelling of the gasket material when exposed to hot engine oil. Provides excellent flange sealing and durability. For original equipment replacement, high performance street, drag race and oval track use. These gaskets are .312 inch thick. That’s substantially thicker than stock which can allow for additional valve train clearance. Fits Chevrolet 262,265,267,283,307,327,350,400 Gen I Small Block with Perimeter Bolt Valve Covers.
