Ok check this out, I took the heads to the machine shop today, and they all got a big hoot, GM had mismarked the casting number, they were both 462's. My machinist showed me a 461. He said he'd never seen one marked wrong before, and thanked me for for providing the grin of the day.
"oohh...thats gonna leave a mark!"
