Srs skill issue during disassembly
If the rods are disassembled and you've been wailing on them out in the open, they're probably all kinds of distorted. I'd recommend getting another set of rods.
An electric engraving pencil is indeed MUCH better than number punches. Costs roughly the same. Not sure why anybody uses punches for that anymore.

If they were out in the open and you wailed on them that way, ... they are now EGGS. GARBAGE. Throw them in the trash.
Since you haven't said anything about that I can't offer any further guidance. Let your conscience help you make the right decision.

Unless you have detonation, there's no "explosive" force being applied to them. Detonation also bends them. Butt even so, combustion pressure is applied to their length, endwise, not from the side where people like to number-punch them; and the force is probably less than you think it is. Blows from the side however, with the other side sitting on a workbench or whatever, WILL egg the big end and the cap. I've witnessed someone destroy a set that way.
Punching them while they're bolted to the crank though, there's no way to deform them, since you're not applying force in a direction that would bend the "ears" inward. All you're doing to it that way, is trying to compress the metal between the punch and the crank. That's safe, won't hurt them.
Can't speak to "observable deformities". I suppose if the bearing bore still mics OK then ... they're OK. I'd FOR SURE at least check them though, if you did in fact try to punch-mark them out in the open.
