Camshaft Identification

I bought this motor from some guy a few hours away from me. I was told it was a stock rebuild, '94 DOHC. I was attempting to set time the other day with Stealthee, and he noticed my cams were very loose.

Turns out, the kid who rebuilt it ended up mixing all the journal bearing for the camshafts (I1, E4). After getting them rearranged I also noticed my camshafts are marked pretty strange, to me. On the front head, my intake camshaft has a D, my exhaust has a B. On the rear head intake is J, exhaust is K.

Do I have camshafts from a 93+ motor and a 91-92 motor? I read in the service manual that 93+ engines were intake is J, exhaust is K. 91-92 engines are intake B, exhaust D.

Any suggestions?
