The MPI Automotive MHF5211 is a 1-3/4in header flange listed to fit the Holden 304 and 308 EFI V8, made from 304 stainless steel. It is the flange plate that headers are built around for those engines.

What does the MHF5211 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 Holden 304 and 308 EFI V8 with 1-3/4in tube openings, and it is made from 304 stainless steel. It is a fabrication component, not a finished header. RRP is listed at $71.08 AUD.

What is a header flange and why 304 stainless?

A header flange is the foundation a fabricator builds a header on: the bolt pattern must match the cylinder head and the tube openings (here 1-3/4in) set the primary size. This one is cut for the EFI Holden V8 head, which differs from the non-EFI pattern. The 304 stainless construction resists corrosion and heat better than mild steel, which suits a stainless header build.

Will it suit my Holden V8?

It is listed to fit the Holden 304 and 308 EFI V8. Because the EFI and non-EFI heads use different patterns, confirm you have the EFI head with the workshop before ordering — the wrong flange will not seal.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men works with flanges like this as part of header fabrication and repair in-house across the Illawarra. We confirm the head type and tube size before cutting or welding. Send your engine details and we will advise on the right flange.
