I run headman long tube headers currently, I'll have to look for the part number. I'll be swapping them out for shorty's or block hugger's pretty soon.

Finding headers that clear the frame, shackle and driveshaft can be difficult.

I just noticed the Hooker comment I posted above was for a 1st gen so you might be fine.
