Okay, all I have is a pic of our Ace valve spring stuff, which is a bit different, but it still has a lash cap.
If you look at the top of that valve, at the very top in the middle of the retainer is a round "button" looking thing. That's not the valve tip. That's the lash cap. It pulls right off, and the valve tip is underneath it.
The regular Bullet has this too, but it's more crude looking.
You can pull it straight up and off with a pair of needle nose pliers.
If your intake valve has a cap on it, and your exhaust valve doesn't, then your exhaust lash cap has jumped off, and it's rolling around somewhere in there. It might be down by the tappets.
