Cross numbers for TTA heads

Sweet6 · Jul 21, 2016

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

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

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