How can you tell if you have a WC or WD head I keep reading it was a common upgrade on the WC I know it has a WD carb on it for sure
 
I don't think there was any difference between a WC head and an early WD head. Later WDs and 45s had a taller head, and while it might be an upgrade I don't think you would know the difference in power.
 
The WC and WD used the same engine. Ya the WD had some different things in the way they where built like hyds for one. The WC, WD, and WD45 engine will bolt up into any of them.
 
The first few years of production did not have the 3-3/8 studs down the one side. You can use a later short head, just can't use the small studs. The later WD's and WD45 used a taller head that more centered the spark plug. You can use that head too, just need the shorter rocker stands, valve cover and tall head studs.
