"X" or "TA" heads???

Hey Guys,
I want to properly identify these heads. I will give all the numbers I found on the head.
3418915 B. Then AAWJ 360. Another tiny plate that is screwed to the head "01090" . There are also several big "U"s stamped on it. It does have 2.02 / 1.60 valves. I looked on three different cast number charts and they all say that they are "TA".
The block is not a "TA" block, it is 2780930, with a 10/5/69 date code.
Are "TA" heads worth more than "X" heads?:popcorn:
THANK YOU everyone!!!:thankyou:
