Default Vendor for LS1 header flanges?

Im going to be fabricating a set of long tube headers for a friend. He is transplanting an LS1/T56 into a 2002 EXtreme chevy truck.

Ive built three sets of headers in the past but they have been either SBC, or GN motor combinations. The last set I built, I had laser cut flanges and they were very nice to use. The previous two sets, I cut my own flanges at the shop I work for using the NC plasma table.

Thats fine and dandy but its tough to get a nice, clean plasma cut flange like a laser cut flange.

Anyway, back to my question.

Does anyone know where I can purchase bare LS1 header flanges? They will likely be 1 3/4" primary tubes so thats something I have to keep in mind.

Thanks

Okay, let me reform my question.

SOMETHING INEXPENSIVE

Stainlessworks is salty.
headersbyed is salty.

There isnt $80 in a set ofo 1/4" thick header flanges. There isnt even $80 in time. LOL
