Kurt or William - Any idea if that 041 head had/was ever off that Z28 that Camaro High Performance documented to see if it was indeed a big valve head?, or was just the casting number & date documented?
Brent396 - Is that Z motor going to be disassembled? If so can you post pictures of the 041 combustion chamber? Also obviously the valve covers were off , did the heads retain the original pressed rocker studs?
Like I said in my post I’m not saying it didn’t/couldn’t have happened , but it would be a rare anomaly for sure IMO .
FWIW - When I worked at the Corvette Shop we once had a 66 327/350 HP Corvette that had never been apart and upon disassembly it had the correct 462” casting heads but 1 head was a 2.02/1.60 head the other was a 1.94/1.50. The casting dates were very close & it still had the GM installed steel shim gaskets, so weird stuff did happen.
Would be interesting to find out regarding if 041 heads ever came with the bigger valves , I have never seen any personally.
