Long tube headers that work with GT40P heads?

[BadShoe]

It's been asked before I'm sure, but does anyone know what brand of long tube headers work on GT40P heads?

Mac longtubes will work.

Thanks, I think I've heard of Mac fitting okay before.

Mike (fast5liter) ran this combo on his 89 gt and everything worked good.
