Problems after cam swap
At this point you need to take a step back. I would do a leak down test and pull the timing cover and verify they are dot to dot. Yes I know you said they are dot to dot but one of the the easiest cam swaps out there turned horrible wrong.
This is not the time to start throwing parts at it. It's time to do some true diag work.

you want both push rods at their lowest point for that cylinder before you bolt on the rocker arms for that cylinder.slowly rotate the engine until both push rods are down and at equal heights for any given cylinder .remember the ls firing order to save time.try to remove the rocker arms the same way ,with the lifter on the base circle of the cam to avoid damaging any rocker bolt threads.

Which 3 pushrods were bent? Random I assume.
A couple of different things could have happened.
Pushrod missed the lifter cup. It's possible.
Pushrod missed the rocker cup. Also possible.
You left out the rocker stands? It's happened.......
Did any of the bolts feel harder to torque? Did you crank them down fast or slow?
And did you have each cyl on the cam base circle when doing this?
