MPI Automotive Windsor EFI Large Port 351 V8 Ford Extractor Gasket.
Category: Extractors and headers


The MPI Automotive EMG206 is an extractor/manifold gasket listed to fit the Ford 351 Windsor EFI V8 with the large-port head. It's the flange seal between the cylinder head and the extractor or factory manifold, not the header itself.
The EMG206 is the exhaust-face gasket for the large-port 351 Windsor V8 in EFI form. It seals each side of the vee where the extractor or factory manifold bolts to the head, so combustion gas stays in the runner rather than escaping at the flange. It is cut to the large-port Windsor pattern specifically — the port window matters on these heads, so a gasket sized to the small-port version isn't the right seal for this one.
An extractor gasket is the replaceable seal between the cylinder head and the exhaust extractor or manifold. Exhaust leaves the head hot and under pressure, so the joint needs a gasket that keeps its shape through repeated heat cycles. On a V8 you're sealing two banks, so each side gets its own gasket. They're renewed whenever you fit extractors, change a manifold, or pull a head — a leaking one tends to tick or hiss under load. It's a routine sealing item, not a performance part on its own.
The EMG206 is listed to fit the Ford 351 Windsor EFI V8 with large-port heads. Port size is the deciding factor here, so the key check is whether your engine runs the large-port casting rather than the small-port one. The supplier hasn't published a year or model list, so confirm your head and flange with the workshop before ordering.
Oak Flats Muffler Men fits Windsor V8 extractors and gaskets in-house across the Illawarra. The job means cleaning both faces, confirming the head is the large-port type, checking the flange is flat, and torquing the fasteners evenly so neither side of the vee is pinched. The EMG206 is supplied by MPI Automotive at an RRP of $33.77; contact us to confirm fitment and book the bay.
