I’m in the process of swapping out springs and the Crane duals require the older style Valve stem seal. I was told that I can use the brown Valve stem seal (Exh Seal) on the intake valves too. Can I? Or should I switch them out for the correct ones?

Thanks!

The brown seals are Viton and the intake seals are poly acrylic. Viton material is designed for high heat applications and is fine to use on the intake side.
Good luck,
