V8 Exhaust Manifold with Cat Differences

[Dingo]

G'day

Ford Tickford have 4 different Part Numbers for these Exhaust Manifolds

XR8 STD/200 - ERTVE-9428/9-A

T Series 200, 220-alloy - TAUTVE-9428/9-A (Coated)

XR8 220 cast - AU3TVE-9428/9-A (Coated)

T Series 250 - TAUTVE-9428/9-B (Coated)

I have 3 of these (2 NOS - 2 Used but haven't done many kms ) 3 have the same Tickford Engineering Numbers on them 1 has different TEN but all 4 have the same AC Delco Cat Number 25315150 on them

in doing some research on the AC Cat number 25315150 i found this refers to a ISUZU (USA) but what model is unknown, also at the time Ford Tickford used these which are a 400cell Ceramic High Flow (Info from Manta on the AC Cat)

Basically want to know are all these interchangeable between the above listed Engines since they all have the same AC Cat ?

any info would be appreciated
