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 3/8″ valve stem diameter
Valve stem oil seals keep unwanted oil from entering the combustion chamber
Several different types of valve seals are offered

Mr. Gasket Embossed Steel Shim Cylinder Head Gaskets are for high performance street machines, drag racing and oval track racing. This is a very unique design that has a solid metal on metal fold at the combustion seal. This fold makes for a very stout seal that is almost the equivalent of a higher-end MLS (multi-layer steel) gasket with a gas stopper layer, but at a much lower cost. This gasket also has embossments around the coolant and oil passages and has a thick aluminum flake coating. All of these features result in a steel shim head gasket that handles extreme cylinder pressures very well. It’s probably the best steel shim head gasket you could ask for. Sold individually.

Product Features:

Embossed steel with aluminum flake coating
Solid metal over metal fold at the combustion seal
Embossed seals at coolant and oil passages
Approximately .020″ compressed thickness
For high performance street, drag race and oval track use.
