Which Headers are these?

[kman71]

These are the headers that are on TTA#1040/Rayder. They were on when I bought the car and appear larger then the stock headers. The stock header gaskets did not fit them. So I am trying to figure out what headers they are and trying to find the right gaskets for them. The only info on the headers is on the front left it has a "C" and the front right it has "1989".

Any ideas or suggestions?

Here are a couple of pics of front and back.

Thats a TTA header that someone port matched slightly.
