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