When the seal hits the bottom of the shaft it is temporarily seated against the head, but when you later finish the spring install and decompress the spring, doesn't the seal come up the valve shaft ~1/8"? Do you need to push it down against the head again?

Once the valve seal is seated, it will not come back up on its own at any point. I hope I understand your question correctly. When the spring is installed and decompressed, the valve stem will come all the way back up from where it was resting on the top of the piston but since the valve stem is not "fixed" to the valve seal and slides in and out of it, the seal won't come up with the valve itself and will stay right where you initially seated it with the socket.
Let me know if this clears it up.
