Polished Aluminum Aussiespeed Holden v6 Commodore alloy rocker covers will fit both supercharged and non super charged engines. Unlike the factory rocker covers that were made from a plastic material and used a rubber gasket, these sand cast rocker covers by Aussiespeed have a machined flat gasket face and use a paper type gasket. No more broken or cracked plastic rocker covers and oil leaking on your exhaust. The top surface is faced with counter bored bolt holes as well as a cnc machined gasket mating face.
The flat machined face allows use of the Aussiespeed diecut paper gasket.
The AS0099/109P do have one oil filler in the standard factory location and use the factory oil cap. Aussiespeed also make the AS0117 oil filler cap cover available in 2 surface finishes and 4 styles. These are also listed in our online store.
Gaskets are included in the package .
Polishing on the V6 Commodore rocker covers is limited to the top face and lower outer gasket face.
