I'm about an hour north of you. There are few guys in the Temecula/Murrieta area that are closer to you.
Your motor does look like it's the original. Although I've seen a couple RR swaps where the stock lowport intake manifold was swapped in along with the stock valve cover (due to clearance issues with the lowport intake manifold) and oil separator/catch can. If you look closely you can see that the tube that fits over the valve cover is either in a different position is a different tube. You'll either have to that head code for us, or have one of us look at your car to verify.
