MPI Automotive FORD V8 BIG BLOCK 460 2in HEADER FLANGE.
Category: Extractors and headers


The MPI Automotive MHF4005 is a 2in header flange listed to fit the Ford 460 big-block V8. It is the machined plate that headers are built around for that engine, not a finished header.
This is a header flange — the plate that bolts to the cylinder head and that header tubes weld into. It is listed for the Ford 460 big-block V8, with 2in tube openings. It is a fabrication component rather than a complete header or exhaust, and its RRP is listed at $92.37 AUD.
A header flange is the foundation a fabricator builds a header on: the bolt pattern must match the cylinder head and the tube openings set the primary tube size. At 2in the openings are sizeable, which suits a big-displacement engine like the Ford 460 big-block where the larger primaries help the engine breathe. Builders and workshops buy flanges like this to fabricate or repair custom headers for the engine. The supplier does not publish a material for this flange.
It is listed to fit the Ford 460 big-block V8 with 2in openings. Because flange dimensions must match your exact head, confirm your engine with the workshop before ordering — the wrong pattern will not seal.
Oak Flats Muffler Men works with flanges like this as part of header fabrication and repair in-house across the Illawarra. We confirm the port pattern and the 2in tube size against your head before any cutting or welding. Send your engine details and we will advise on the right flange.
