Cross numbers for TTA heads

[Sweet6]

What are the other casting numbers that work on the TTA? I know there was a couple but I forgot where I saw the list.

Thanks

515's and 248's are close .. but not exact to the TTA heads

25536702 is the original casting #

I knew the 515s were a cross but wasn't sure about others.

Thanks

There is also a 25523030 cylinder head. I could be wrong, but I think it was a warrantee replacement back in the day.

I thought the 030 was one too
