How'd you come by them? It sounds like they're telling you that the heads aren't theirs... Here's a pic of mine:

i looked there and only thing i found is 021 .but that doesnt match anythn according to them .heads have patriot stamped on the side right above the last exhuast port.

Perhaps you have really old ones? But stamping is common, any spot that looks deburred where the 4 digit is possibly missing? Just a thought...

How much did you pay for them? Didn't the seller tell you anything?
