According to the parts catalog, which is usually pretty bang on, all 1972 an 1973 Torinos, Police interceptor or otherwise used the same manifolds. The right side manofolds on the 72 and 73 cars shows interchangeable with the earlier CJ/SCJ engines.  So, basically the way I read it is, all big block 1972 and 1973 Torinos get the good manifolds.
 
That said, the 1972-72 Fullsize Fords and Thunderbirds used the standard manifold.  Only the fullsize Ford police cars with the interceptor engines got the good Torino manifolds.

My 460 in the Gold '72 Formal has van manifolds. They are supposed to flow better than stock Torino manifolds but not as good as CJ versions/headers. That is basically the reason for me not stepping up to headers.

Joe, that was my thought, these would have better flow than stock without the possible fitment issues of the headers.  I will be checking on getting it repaired and if possible will be using these.  Thanks to everyone for their input  -  dave

Hi Everyone,   Just reviving this thread to help identifying exhaust manifolds I have.    I picked up a 1972 Ranchero 429 N code. I knew the guy that owned it, & he was a Ford Guy. Anyway, I haven't been able to ID the manifolds on the car, but there were 2 manifolds inside behind the seats. 

D20E-9430-CA
D20E-9431-AA 2

I am curious if these are PI manifolds?  or ?  Any help to ID them would be helpful.

TIA
