RHS™ Pro Elite™ GM Gen III, LS1, LS2, LS6 Cylinder Heads
CLICK HERE FOR INSTALLATION NOTES
OVERVIEW
FEATURES: Fully CNC-machined runners
Fully CNC-machined chambers
11° valve angle for maximum flow
Steel rocker stud boss inserts
Fits all GEN III intake manifolds
0.500” raised valve cover rail
Highly efficient water jacket design
Massive 0.800” thick deck surface
Improved valve guide design
As part of the Pro Elite™ series, new RHS™ Gen III aluminum cylinder heads are fully CNC-machined for superb finished quality and maximum airflow. A massive 0.800” thick deck surface dramatically increases the structural integrity of the casting, making Pro Elite™ Gen III cylinder heads perfect for high cylinder pressure applications such as turbo or nitrous. Another benefit of the increased deck thickness is that it yields a combustion chamber that can safely be decked to 36cc for increased compression and power output. Steel inserts strengthen the rocker stud boss area, and casting integrity is further improved via the triangulated exhaust ports and hardened steel head bolt washers.
Raising the valve cover rail 0.500” allowed for the creation of the raised roof ports. Best of all, the RHS™ design team has re-engineered the valve placement, rolling it over 4° from stock to create an 11° valve angle. The result is additional free drop spacing to accommodate high lift cams without piston interference and dramatically increased volume, velocity, and atomization in the intake ports. So if you’re looking for a set of GEN III cylinder heads that combines uncompromising quality with unparalleled performance, look no further than the Pro Elite™ series from RHS™, the only GEN III cylinder head on the market that delivers Power By Design™!
This seal ensures that all heads professionally hand-assembled at RHS™ headquarters use industry leading COMP Cams® components for maximum durability and performance
PRO ELITE™ GEN III FULL CNC - 210cc Runner
The new RHS™ Pro Elite™ 210cc GEN III cylinder heads are the perfect bolt on head for medium-displacement LS1 style street engines. Ideal for 5.7 and 6.0L engines, Pro Elite™ 210cc cylinder heads have been dyno-proven to make from 450 to over 500 rear wheel horsepower, and over 650 flywheel horsepower in naturally aspirated trim using common performance parts. With a massive .800" thick deck, Pro Elite™ 210cc cylinder heads make cylinder head lifting and blown head gaskets in high boost pressure and nitrous oxide applications a thing of the past.
