I am considering another production run of unique header/exhaust manifold flanges:
They will be laser cut from 0.5 inch 304 stainless steel (thicker than most competitive flanges). The perimeter design of the head flange is unique and is meant to isolate each runner. This is to prevent warping or buckling of the flange after repeated usage as well as shearing manifold bolts. I also believe that the curves yeild a more attractive finished manifold. Here is a little inspiration for winter projects:
Each head flange will be $75 shipped to anywhere in the continential US. If there is some interest, I will do a small production run and make a FS post. If someone was interested in a custom flange (add logo, initials, devil horns, whatever), I could accomodate that for similar money.
