 Nice !!    Now I don't have to hunt the good ones down .     Gonna order some right now !   Important to have good Valve Stem seals that hold up.    What with the copious amounts of oil being squirted at the springs and valve stems....

For those who don't know, Viton is what I would call the Superman of the seal materials.
It's strength is excellent, it doesn't wear out, it doesn't break down and it is resistant to almost all of the chemicals that would ever be used around a motor vehicle.
It's only weak point is it is rather expensive.

When you look at the cost vs the benefits of using it, paying the extra money is, in my opinion, well worth it.
