Part# AS0215P - Pair of Polished alloy Pro Street Style panel top AussieSpeed valve cover for a 8 cylinder Holden V8 engine. This rocker cover is made to clear Yella Terra roller rockers on 253 and 308 engines. It is made from sand cast aluminium, it is thick and comes with rubber grommets to take readily available aftermarket standard PCV and push in breather caps.

These AussieSpeed Holden V8 covers have a molded inner drip lip to help prevent oil leakage by holding the gasket in place, funnel style cast in breathers to stop oil splashing up at the breather and PCV, & are tall enough to clear most roller roller rockers, however in some instances with large rollers the oil baffle may need slight clearancing when fitting them up.

Large diameter valve springs up to 1.375" OD are ok. Springs over 1.375" in diameter will need relief notches machined into inside edge of valve cover.  The valve covers are approx 5 to 6mm thick in this area.

AussieSpeed V8 Holden Rocker covers are 110mm tall outside & 90mm tall on the inside. std factory tin covers are,77mm outside & 76mm inside
