VERY nice find. So nice in fact you may want to purchase a different cover and conserve the "Surf" cover as the "Hot Frames" are going for some nice change right now.
@p_kos & @rhwestfall pretty much nailed your question. If your second stages have not been upgraded with the new s-wing poppet then I suggest you do so. Store | Vintage Double Hose &/or @buddhasummer can help you out with the parts and service kits.
