^^ I was actually gonna mention the two outers too, but I figured by studded you meant all studs.
That's really weird, then, that my old engine had all studs, yet your 96 did not. It was the original engine to the car, OBD2 and all, and I distinctly remembered the studs because when I made the swap to my JDM ITR engine, I had to scramble to find 7 bolts that fit for the header.
The only thing I can think of is maybe 94s, 95s, and early production 96s had the studs, then they did away with them after that. My car was assembled I believe September or November of 95.
