My 70 Trans Am Ram Air III was also this way. It was a WS block. Back in the day, I questioned whether someone had changed the caps for some reason. Later found out this was quite common. Saved Pontiac the cost of 6 bolts, and a tiny bit of iron to make the larger caps. Possibly $1.00-2.00 per car. That was a big savings at the time. Kinda makes you sick doesn't it?
