Take the push rods out and see if the motor will spin. If it does, turn it over until both lifters for one cylinder are at their lowest setting. Loosen the lock nuts and adjust the lifters to the lowest setting. Install the pushrods and then adjust them until the pushrods will just spin without binding. Tighten the locknuts and verify that the pushrods will still spin. Rotate the motor and repeat for the other cylinder.

Yes, the crank needs to be in the right place when you time the cams, but use the mark on the pinion gear, not the timing mark.

Yeah. And it has to be installed on the pinion shaft in the right position. Did you remove the pinion gear from the pinion?
If the engine was on tdc and the pinion gear was in the right place, everything should work when the marks are lined up.

There should be a mark on the pinion shaft and on the pinion gear. They should line up. When they're lined up the mark on the pinion gear needs to be at about 11:00 o'clock pointed towards the center of the rear intake cam bearing.
If you didn't remove the pinion gear from the shaft and it's pointed that direction and all the cam timing marks line up, then you should be in good shape.
