The MPI Automotive MHF4000 is a 1-5/8in header flange listed to fit the Ford 351 Windsor V8. It is the flange that headers are built around for that engine.

What does the MHF4000 cover?

This is a header flange — the machined plate that bolts to the cylinder head and that header tubes weld into. It is listed for the Ford 351 Windsor V8 with 1-5/8in tube openings. It is a fabrication component, not a finished header or exhaust. RRP is listed at $71.08 AUD.

What is a header flange and who uses one?

A header flange is the foundation an exhaust fabricator builds a header on: the bolt pattern must match the cylinder head and the tube openings set the primary size. At 1-5/8in this flange suits a milder street build of the long-serving Ford 351 Windsor V8. 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.

Will it suit my Ford 351 Windsor?

It is listed to fit the Ford 351 Windsor V8. 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 1-5/8in tube size against your head before any cutting or welding. Send your engine details and we will advise on the right flange.
