I have new rockers.
My concern about the swath being outside of center was the reason for my initial question.

I think I misunderstood your initial post. I was thinking side to side, meaning if I look at the valve stem from the side of the car, the pattern is slightly to my left or my right. I fully agree that the pattern in and out could change after torquing the heads. Only way to find out is to torque it down.
Slightly off center (in and out, not side to side) would not worry me. Ideally, you want it right in the center. I have a couple of adjustable test push rods that I use to dial in the perfect length, then go hunting for push rods. Of course, I am guessing the 409 doesn't have the same dizzying array of push rods available as the SBC.
