Is a X head 894 casting only

Many old sources for Mopar info were later found to be wrong!
I think the first Direct Connection manual I had claimed that all '68-'71 340s were X.
We later discovered that '71s didn't have the X head.
So the seller may have seen this info repeated over the years and believed it was gospel.
Hopefully not trying to deceive you! If a '71 casting it should have a 2.02 intake valve if 340 not 360.
