RHS Pro Elite SBC 23-Degree CNC-Ported Iron Cylinder Heads

Engineers at RHS have recently designed the only Small Block Chevy 23-degree cast iron head 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 precision CNC-porting of the intake and exhaust runners but the CNC-ported combustion chamber, as well.

Before CNC machining even occurs, these revolutionary cylinder heads are designed using the RHS exclusive Clean Cast Technology to deliver superior port-to-chamber transitions for greater airflow. The CNC-ported 228cc intake and 82cc exhaust runners optimize volume, atomization and velocity while the 69cc combustion chambers are CNC-ported to relieve valve shrouding that occurs in “as cast” chambers when the edge of a valve is in close proximity to the combustion chamber wall. By CNC-machining the combustion chamber, RHS was able to improve the airflow efficiency of the cylinder heads.

The 2.055” multi angle intake and 1.600” radiused exhaust valve seats allow for superior airflow, thereby significantly increasing horsepower. In addition, these 23-degree SBC heads feature a refined water jacket for more even water flow to reduce engine “hot spots” and an extra-thick deck to allow angle milling. The thick deck surface also improves head gasket retention in boosted and nitrous applications. For racing classes that mandate cast iron head use, RHS has designed a race-winning cast iron head that utilizes the latest in cylinder head technology.

Poly Performance Double Adjuster Tube Adapter

The Double Adjuster Tube Adapter is ideal for steering and link suspension designs with weld-on bushings/joints at one end. Bent link applications are also ideal, as the double adjuster tube adapter provides precise adjustment without twisting the link out of position. Common applications are: custom tie-rods, control arms, drag links, track bars, trailing arms, and 3 or 4-link suspensions. The weld-on Tube Adapter is manufactured of solid 1018 steel and when installed, it seals the tube from water and debris preventing corrosion damage from within the tube.

Poly Performance Double Adjuster Tube Adapters are available in 5 sizes, 7/8"-14 for 1" ID tube, 7/8"-18 for 1" ID tube, 1"-14 for 1 1/4" ID tube, 1 1/4" for 1 3/8" ID tube, and 1 1/4" for 1 1/2" ID tube. Each set is sold with one Weld-on Tube Adapter, one Zinc plated Double Adjuster Sleeve and 1/2" Pinch Bolt hardware. A retail price of $50.00 is suggested.
