High-flowing cylinder heads for your engine.

These RHS Pro Torker small block Chevy cylinder heads outflow all previously available small block Chevy cast iron cylinder heads. In comparison to the popular GM 906 casting, they flow 27 more cfm at 0.500 in. lift, right out of the box. Made from premium-quality cast iron using RHS' patented Clean Cast Technology, the RHS Pro Torker small block Chevy cylinder heads deliver a competitive edge in racing classes where iron heads are required. The heads come standard with radiused hardened exhaust seats, multi-angled intake seats, and "Fast Burn" 64cc combustion chambers. To ensure maximum versatility, they feature dual-pattern intake compatibility to allow use with virtually any intake manifold, early or late. They are also equipped with 1.550 in. valve spring seats and valve guides engineered to avoid retainer-to-guide clearance issues when used with high-lift camshafts. The RHS Pro Torker small block Chevy cylinder heads have overcome all of the shortcomings normally associated with OEM Vortec heads. So, if you're in the market for superior-performing cast iron cylinder heads, remember that RHS delivers the ultimate in high-quality, high-flow technology with its new Pro Torker small block Chevy cylinder heads.
