Light Headed
Racing Head Service (RHS) has designed a 24-degree, CNC-ported big-block Chevy cylinder head that features multi-angle intake and radiused exhaust-valve seats for up to 5 percent more airflow and increased horsepower. A thick deck surface allows these heads to be angle milled and provides increased rigidity to improve head-gasket retention in boosted and nitrous applications. The best features, however, are the CNC-ported intake and exhaust runners for optimal air volume, atomization, and velocity. The heads are available with either a 339cc or 376cc runner volume and a 121cc combustion chamber. For more information, visit www.racingheadservice.com.

They're available for both the driver (LH) and passenger (RH) sides and are sold individually. Check out www.volvette.com for more info.
