PH 4020 Falcon XR-XY 289-302 Windsor with Standard Heads.
Category: Extractors and headers


The Pacemaker PH4020L_R is a matched left/right extractor set listed to fit the Ford Falcon XR–XY running the 289 or 302 Windsor V8 with standard heads. It replaces the cast factory manifolds on the classic small-block.
Extractors, or headers, bolt to the cylinder heads in place of the original cast exhaust manifolds. This set is cut for the 289 and 302 Windsor with standard heads — the head casting matters because port and bolt patterns differ, which is why the listing calls it out. On an early XR–XY Falcon they're the starting point of an exhaust build, ahead of whatever pipework and muffler follow. We publish no flow, power or sound figures and won't fabricate any.
It's listed to fit the XR through XY Falcon with the 289 or 302 Windsor and standard heads. If your engine runs aftermarket or non-standard heads, that changes the fit, so confirm your exact combination with the workshop against the listing before ordering. The L_R suffix means a matched left and right pair.
These are extractors rather than a catalytic converter or muffler, so they carry no emissions approval of their own. Whether the finished exhaust suits NSW road requirements depends on the rest of the system and how it's engineered on a vehicle of this era. No compliance approval is published by the supplier, and we won't claim one.
Oak Flats Muffler Men fits classic Falcon extractors like the PH4020L_R in the Illawarra. On an older car we check head type, steering and chassis clearance, fit fresh gaskets and seal the joints before tying into the system behind. We confirm the listing matches your Windsor build first. RRP is listed at 1066.85 AUD; fitting is quoted once we've seen the car.
