Default 330545 Cylinder Heads

Hey guys- How rare are the 330545 cylinder heads? They're a one or two year 73-74 small block L-82 head. I have a 73 L-82 with a set of 487X heads on there, certainly incorrect.

"...73 L-82 with a set of 487X heads on there, certainly incorrect."

330545 are shown for 72-75. Though maybe not stock 487X would not be incorrect, instead a good choice. (71-73)

Why do you say is the 487X is a good choice? 67 cc chambers? Hardened seats? Wouldn't I be better off with a set of 3972186 Chevrolet heads if I cannot find a good set of correct 330545's?
