I think they knew the heads were bad, and they dumped them on him.

The deal was, he kept what was good, and returned the rest, no one thought that there would only be only 3 good heads in that batch. I'm friends with both the owner of the yard, and the guy looking for cores. Just a lot of wasted effort for only 3 good core heads. GM put out a lot of crap during that time and lost their market share because of their greed.
Neither party knew what was good, or bad, until it was all over with, and neither party was trying to misrepresent the goods. I know the guy that was looking for good cores wouldn't have even started the project if he had any idea there would only be 3 usable heads out of the bunch, he was pissed he only got 3 cores for all that work.
Of course not every batch of 100 heads were defective to that ratio, or else no one would have bought their cars. (I never implied that in the post either..
) There were 2 bad casting numbers that people steered clear of that were later identified, at that time no one yet knew what the ones to be avoided were.
This was right at the beginning of the bad heads, bad cams, SBC debacle. In 1978 I had a 305 1977 chevy Caprice with 17,000 miles with bad guides come in my garage for a ticking noise. At that time if you got 65,000 miles from the late chevy 305, you were blessed. The money making 305 tune-up was common in the late 70s early 80s. It consisted of new cam, lifters, timing chain and gears, pull the heads, and repair the guides and valves that were bad, and a valve job. If the heads were cracked, then new, or good used, needed to be procured. I did dozens of them myself. GM pushed a bunch of loyal customers to other brands during those years, that never returned.
