I thought you said there was no engine block with this project, it's just pieces and the heads. If that's correct then the internal used pieces he has are worthless, they are dirt cheap to buy new...no one uses used parts when rebuilding a SBC.
If you're buying an original Cameo and you have proof it's not a clone AND you have to rebuild everything anyway because it's a project, then why not build it with the correct engine? The engine parts the seller has now really don't matter because you won't use them anyway. Find an original engine and build the truck back stock, anything less will cost you thousands when you go to sell it.
