Part#AS0126 - AussieSpeed. 10mm thick CNC machined from biller aluminium. These spacers have been used by falcon & Cortina owners to give extra clearance when fitting roller rockers. For owners of the 4.1 fuel injected engines as used in XF Falcon ,wanting to run Yella Terra adjustable roller rockers please note our 12mm rocker cover spacers will lift your factory Aluminum valve cover to clear the rockers but the cover will foul on the plenum. We have a 6mm thick version also listed here at KustomBitz which is more suited to the EFI model.
