What parts are worth keeping off of a /6

Thanks for all the replies, i just figured if it was to be rebuilt that i would have it bored over which would require new pistons, im assuming aftermarket cams and valve terrain parts are available still for the /6? I will definitely keep all the internals, i need to get it at least up on a engine stand and remove the water pump and other stuff, i would like to tear it down to see the condition, so it does have a forged crank?

My long term dream would be to find a duster or dart to put it in and turbo it but thats not in the cards at the moment
