6.5 TD Head ID number

[Turbo Al]

Hi just trying to firgure out what heads I got here. I bought a wreaked 94 pickup that has had some engine work done to it. It has #12552929 casting number so I believe it may be the original 94 block but the heads are obviously either new or rebuilt #61781 = Pas + #61782 = Dr. -- I was told the top end was done two years ago. So are these the original heads rebuilt or from a later model year??
As always thanks in advance.

My head casting number list covers 1982-93.... Your number isn't on my list. Maybe others will chime in...

The block is for a '95, possibly late '94 though.

There should be a casting number on an exhaust port that bears the correct number you're looking for.

But, they did move them on certain years...

These #'s are stamped in the intake side of the heads which leads me to believe they are aftermarket heads or heads were reworked by someone then stamped.

the casting #'s are hard to read
Pass are F083 567
Dr may be something like 10137567
10187567
the only #'s that are clear are the 7567 rest is pretty messed up.
Thanks for the replies

taking apart my reman 6.2 I found it to be a 506 block. the heads, for all my searching the only number I can find is on top between rockers. it is F046. Are these 6.2or 6.5 heads?
