HQ-5800-04 flexible viton valve seals

Used on all Head Quarters Evolution and Twin Cam valve guides.

These are the absolute best seal money can buy. Their ability to move around with the valve while maintaing a strong grip on the valve guide make them leak and problem proof. Nobody wants to have a job fail over a 50 cent part. These seals are the cheapest insurance you will ever buy.

Above seals also available in quantities for shops and cylinder head builders.
