Default C5 Z05 exhaust manifolds - casting number?

In the process of collecting stock parts that didn't come with my Z when I bought it.

Came across a seller with a set of manifolds that are supposed to be off a C5 Z. Any way to tell such as a casting number or part number?

Thanks.

I checked mine but couldnt really see much of the manifold with the heat shields on them. Did a search though and found this, looks like it should answer your question.

Just to be clear, ALL 120,000 or so C5's made from 2001-2004 used the same cast iron exhaust manifolds(nothing special here on the Z)

Ironically it's the 12561256 repeat number.........you'll see 1256 often as a prefix on the C5 and 1255 for the other manifold

I thought the C5Z's had a thinner manifold wall for weight???

I have some manifolds from my 2003 Z06 I'm wanting to sell, includes oxygen sensors and heat shields. They have about 18k miles on them. PM or email kerryt1 at gmail dot com if you're interested.
