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.

Torque capacities of nearly 1,700 lb-ft are possible, depending on disc options. For more info, point your browser to www.specclutch.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.
