The MPI Automotive EMG170-GRPA is a Group A exhaust gasket with round ports, listed to fit the Holden VN to VS 5.0L. It seals the exhaust joint at the head for the round-port Group A application on that V8.

What is the round-port Group A gasket about?

This gasket is cut with round ports to match the Group A head arrangement on the Holden VN to VS 5.0L, as opposed to the standard port shape. The round-port design means it has to be matched to that specific head rather than a generic VN–VS gasket. It is a consumable sealing part that seals the flange between the manifold or extractors and the head; it is not a performance part itself.

Why does port shape matter?

An exhaust gasket only seals properly if its port openings line up with the head's ports. The Group A round-port heads use a different opening to the standard ones, so the EMG170-GRPA is the matching gasket for that variant. Fitting the wrong port shape can leave the gasket overhanging the port or blocking flow, which is why the round-port version is called out.

Will it suit my Holden VN–VS 5.0L?

The EMG170-GRPA is listed for the Holden VN to VS 5.0L in the Group A round-port configuration. Confirm that your heads are the round-port Group A type with the workshop before ordering, since the standard heads take a different gasket.

What does fitting involve at our Illawarra workshop?

Oak Flats Muffler Men supplies and fits these gaskets in-house across the Illawarra. We fit the EMG170-GRPA against the round-port flange, clean the faces and torque it evenly so it seals. Supplied by MPI Automotive at $64.34 AUD.

Stocked and fitted by Oak Flats Muffler Men, the Illawarra exhaust and 4x4 specialist in Oak Flats, NSW.
