Spark Plug Heat Shield ID Help Please

[VetteSpaz]

Can anyone of you out there please help with the identification of what year these spark plug heat shields came from? I'm betting that they may have come from a '70s GM big block engine?

Thanks to the experts in advance,
Mike

They look just like the ones I have on my 72 Chevelle

Thanks Jake. Is your Chevelle a 396?
