FORD V8 351 WINDSOR 1 5/8in HEADER FLANGE (MHF4000) fits selected vehicle applications. Fast.
Category: Extractors and headers


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.
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.
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.
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.
