Since 69 production went till Dec. of 69, that date should be good for late production 69's.

I need to clarify my post. The heads did not come off a Corvette to my knowledge. I believe they were taken off a Chevelle but not sure what year. I assumed that both Corvette and Chevelle changeovers happened in August of '69 but apparently that was an odd year for Vettes and they ran thru the full calendar year. I had forgotten or was not aware of that. In any case I think the spark plugs were different between '69 and '70 in those heads which is what I was actually trying to pin down. As far as 291's being used in Corvettes...one of the listings show them with an application in 435 horse 427's so I would suppose that would be for a Vette. I am not sure if any of the other Chevy models had that combination other than Corvettes.
