Brand new set of 16  Full Viton Valve Seals, Metal Clad.  These are 11/32" stem X .530" diameter. Fitment: aftermarket cylinder heads that use 11/32" valve stems. Will fit these applications

These are not the design that are not Viton all the way down. Much easier to install and stay compressed onto the guide much better.

We are the manufacturer and use thousands each year in our own engine and cylinder head shop. Don't buy from a no name importer. Buy from one of the top names in muscle car engines in the world, Butler Performance.
