BIG BLOCK CHEV FABRICATED VALVE COVERS BLACK BBC

Aeroflow's Fabricated Rocker Covers are made from 5051 aluminium. They have a one-piece billet rail CNC machined from 6061-T6 aluminium to guarantee a precision flat surface for superior sealing. They come in either polished or black anodised finished. The covers come standard with a female -8 ORB (some are available with -12) for breather applications and a threaded o-ringed billet oil filler cap. All covers are tall enough to clear 99% of rocker combinations.
