Vortec Heads for Small-block Chevy
October 15th, 2009
The new RHS(tm) Vortec Iron Performance Cylinder Heads deliver superior flow characteristics over all other forms of iron small-block heads previously available.
In comparison to the popular GM 906 casting, the RHS Vortec cylinder heads deliver 27 more cfm at 0.500-inch lift. Featuring dual pattern (four- and six-bolt) intake compatibility, these heads work with virtually any intake manifold (including early style) rather than being restricted to Vortec-style components, which has been a limiting factor in the past. Equipped with hardened exhaust seats, multi-angle performance inlet valve seats and “Fast Burn” 64cc combustion chambers, the new RHS Vortec heads are perfect for both race and street performance applications.
