Jim.  From a performance perspective, those heads are simply in the middle of the list making many of the bigger valved heads more desirable.  From a restoration standpoint or where someone is trying to make a 182HP 272, then they would be worth more than simply core pricing.  From a performance standpoint, these would still be a better cylinder head than any of the heads made for the Y after 1960.
 
I did recently dyno an original 1955 182HP 272 that had some miles on it.  It still managed 177HP with the Teapot carb and L-O-M distributor with the old spark plugs, wires, and tune up in place.  With a rebuild which included a 0.030” oversize bore, an Isky E4 cam ground on 112°, and some mods to the inside of the Teapot intake manifold, this engine was up to 207HP.

Thanks Ted,  I appreciate the information. even though I played with these  Y-Blocks when I was a teenager, I really never knew a lot about them, and am now trying to improve my knowledge of them.----Jim
