The MPI Automotive MHF721 is a 1-3/4in header flange listed to fit the Chevrolet Silverado 6.2L. It is the flange that 1-3/4in extractor tubes mount to at the cylinder head.

What is a header flange?

A header flange is the machined plate that bolts to the cylinder head and that the extractor primary tubes weld into. The MHF721 is sized for 1-3/4in tubes and cut for the Chevrolet Silverado 6.2L head. It is a fabrication and fitment part rather than a finished extractor or a performance part, giving an even face for the tubes and the gasket to seal against.

What does the 1-3/4in spec mean here?

The 1-3/4in figure is the primary tube size the flange is designed to accept, so it matches extractors built with 1-3/4in primaries on the 6.2L. Knowing that tube size matters when fabricating or repairing a header, since the flange holes have to suit the tubes that weld into them.

Will it suit my Silverado 6.2L?

The MHF721 is listed to fit the Chevrolet Silverado 6.2L. Confirm your engine is the 6.2L with the workshop before ordering, since the flange has to match that head's bolt and port pattern. It is aimed at building or repairing extractors rather than being a bolt-on finished part.
