340 T/A head identification

T/A heads are specific to T/A blocks which came in RT Challengers and AAR Cudas
these are six pack motors the push rod holes are in a different location and the
rocker assembly matched the hole configuration. You should post some pictures
of them for proper I.D. This are of value to a guy building a TA engine but thats
about as special as they get, the port size and valve size are the same as any x heads.
