1986 Olds 307 valve seals

I just ordered these Fel-Pro replacement valve seals # ss70393 for the 307 in my Regal from a local Advance Auto does anyone who if these engines also use an O-ring on the valve stem.
I want all the parts needed here before I start working on it.

The exploded view diagram in my 84 shop manual does show any O-rings.

Do you mean does NOT show any O-rings?

 

[HOAdrian]

That is correct. No O-rings. My brain and fingers do not sync up all the time.

Those are it, believe it or not. Olds never had the valve guide issues the SBC had, therefore the basic style plastic seals were used. I have had the center exhaust seals melt when my water pump fell apart on the 307. My current Olds 350 has positive seals but those require valve guide machining.
