Valve stem seal colors
I bought a gasket kit for a 94 bronco 351w. Sealed power part #260-1731. The kit has 3 sets of valve seals. Red, blue and black. The red are marked as premium. Which color goes on the intake and exhaust valves as nothing is marked.

For your application, use the black seals for the exhaust and the blue seals for the intake.
