Engineers at RHS have recently designed the only Small Block Chevy 23-degree cast iron head for 360-434c.i. engines that is CNC-ported from the factory. The precision accuracy and durability of the RHS Pro Elite SBC 23-Degree CNC-Ported Iron Cylinder Heads are derived not only from the CNC-porting of the intake and exhaust runners but the CNC-ported combustion chamber, as well.
The CNC-ported 240cc intake and 85cc exhaust runners optimize airflow volume and velocity while the 53cc combustion chambers are also CNC-machined to relieve the valve shrouding that occurs when the edge of a valve is in close proximity to the combustion chamber wall. Overall, the full CNC-porting process provides more consistent runners and smoother port-to-chamber transitions, thereby increasing both airflow efficiency and horsepower. In addition, these new heads from RHS are designed to use offset rockers in order to maximize the intake window at the pushrod opening for increased airflow.
As with the rest of the Pro Elite family, these SBC iron heads come with a host of unique features, including premium bronze valve guides and a multi-angle valve job. Also, ductile iron valve seats are inserted to better prevent seat and guide wear with alcohol and other racing fuel applications. The ductile iron 2.100" multi-angle intake and 1.625" radiused exhaust valve seats allow for superior airflow and improved atomization with racing fuels. In addition, the heads feature a refined water jacket for more even water flow to reduce hot spots in the engine. For racing classes that mandate the use of cast iron cylinder heads, RHS has designed the ultimate advantage by utilizing the latest in airflow technology.

Del City now offers new stainless steel cable ties. They can withstand harsh, corrosive and salt-water environments because they are resistant to chemicals, radiation exposure, and temperatures up to 572° F (300° C). Each cable tie is manufactured from #304 stainless steel which produces little to no oxidation, making them the ideal choice for clean environments. Del City's new stainless steel cable ties feature a self-locking ball mechanism that meets low insertion force requirements, while maintaining a 100 lb. tensile strength.
Del City has also added the Cable Wraptor, precision lock cable ties and Grip Strip cord organizers to complete our new line of cable bundling accessories.
