Are there any numbers on the other pan rail?
E1NN and the date code of 6A20A suggest to me that the engine was built up on Jan 20 1986. If you're sure it's a 4.4" stroke crank then you're definitely ordering parts for the wrong engine. Given the other numbers I'm kinda of the mind to say it's a 268 or a BSD 444.

If you have a 268 engine (4.4 stroke), and you are ordering parts for a 256 (4.2 stroke), then yes, you indeed have the wrong pistons.

Take those numbers to the dealer and have him double check them and make sure it's a 268. There's a lot of different pistons avaliable even for a 268...

Rod,

What else could it be if the crank has 4.4 cast right on it?

If it's got 4.4 cast on the crank... I guess it's a 268. To be honest, I forgot that he posted that in an earlier post.
It's still nice to know with certainty what the engine is exactly. You know as well as me that there's some very tight unit code breaks on specific parts on those engines, particularly around the water pump... that he ought to know even if it's not overly relevant to ordering pistons.

If the bore is 4.4", and the stroke is 4.4", then it's a 268. Period. End of story.

About the only other thing you need to be aware of is the difference between turbo and non-turbo pistons. Non-turbo pistons will stick up about .010" taller than non-turbo pistons. You want a non-turbo engine's piston protrusion to be about .011-.023" above the top of the block at TDC.

Yeah... if it's got a 4.4" bore and 4.4" stroke it's a 268 but that doesn't mean every part is the same in all N/A 268 engines. Most things are exchangeable as sets but you would not want to mix and match pistons from different generation engines....

Oops, I meant to say non-turbo pistons stick up taller than turbo pistons. Turbo engines have a lower static compression ratio.
