MPI Automotive Holden 304-308 EFI V8 1 3/4in Header Flange.
Category: Extractors and headers


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.
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.
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.
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.
