Proflow's new Holden V8 fabricated aluminium valve covers deliver high-end looks without the high-end price! Constructed from AL6061-T6 sheet aluminium and precision TIG-welded for a proper fit, they feature thick one-piece CNC machined billet flanges for superior sealing capabilities. They come with female AN8 ORB breather ports at the front of both covers and are tall enough to clear most popular rocker arm combinations. Supplied with mounting hardware and are available in a powder coated black or natural aluminium finish.
