1/2” Thick 304 Stainless Laser Cut Flanges. Made for the 3.2 VR6, great sizing for 1.5” Weld Els, for those custom Turbo Manifolds. Also fits up great on the 2.8 24 Valve head, all though the casting on the exhaust ports is a tad bit smaller then the 3.2 head. 2 flanges help keep the warpage to a minimum, Flanges might be .015” out of flatness, due to sheet material used when laser cutting. After the welding process is done, manifold flanges should be decked flat.
