LT header id

[djj62478]

Hey guys I'm new here. Have a 90gt that I somewhat recently picked up. Got the motor out doing a swap and the car has these headers on there. Can't find any identifying marks and was wondering if anyone is able to id them?

I think Mac had the separate flanges like those.
People had a hard time reinstalling them due to warpage.

I like my separate flange LTs, yeah a little quirky but not hard, I thought mine were BBK but honestly it was a while ago.
Mine may be a little less 'rustic' than those, sorry.
