FS: 1/2" header flanges, to your specs, limited material available

i have a good sized piece of 1/2" material i want to use up, its approx 36" x 18" which is big enough for about 9 sets of v6 flanges. i personally need 2 sets, so the rest of the material is just extra,

the material has one nice side and one some what scratched side, and both sides have been cleaned up w/ a sanding disk on a grinder. a pass or 2 w/ a belt sander would net a nice neat appearance. the surface finish is no rougher then a normal machined finish, so there wont be any sealing probs

i can convert a scan of a exhaust gasket into a cad file, as long as im given reference measurements in the process so i can scale it properly

anyone interested ?

I have cad files of flanges I would like, but how much?
