Valve stem seals

Is there a kind of valve stem seal for small Chevys that looks similar to a normal o-ring, only square not round? What motors and years would it fit? I found 16 of these rings in my Felpro gasket kit but this is not how I expected a stem seal to look like.

Regards
Martin

Those are the original style valve seals for the two-groove valves. There are used every day in about two bzillion GM engines.

Ok, so I can expect a 1980 305 to use these stem seals? I actually need to change them but haven't removed a spring yet to see what's there.

The O-ring seals were used up till the early-mid ninetys. Even after the engines went to positive seals.

When you remove the valve locks and retainer you will see two grooves in the valve. The lower one usually has a hardened semi-brittle old seal in it.

When you re install the assembly. Just before installing the locks. Slip the seal over the valve and locate it to the lower groove.
