RHS® carries all the accessory items and tools needed to maximize performance with the LS-Series Gen III/IV engine blocks
The LS Race Block from RHS® has revolutionized the GM performance aftermarket. And now RHS® provides the tools and accessories necessary to go even further and turn any LS application into an all-out racing engine, including torque plates, head gaskets, main cap pullers and intake spacer kits.
RHS® Torque Plates for boring/honing are carefully engineered to precisely mimic the thickness and design of an installed aluminum cylinder head. When assembled with the torque plates, engine block stresses and bore distortion are accurately replicated during the machining process, thus more precise boring and honing is reached for maximum performance. Exclusive RHS® design – don’t accept inferior deck plates, and never use a steel or cast iron deck plate on an LS engine. Engineered to work with all LS engine blocks, including 6-bolt LSX pattern blocks, this is a must-have for any serious RHS® LS Race Block engine builder.
RHS® precision MLS (Multi-Layer Steel) Head Gaskets are custom made for an exact fit in LS race engine applications. They are comprised of three layers of hard embossed stainless steel with a high temperature FKM rubber coating and a stainless steel shim layer that features a laser welded stopper layer for the ultimate in combustion sealing. MLS Head Gaskets are perfect for high horsepower, high boost, naturally aspirated and nitrous applications. Easy-to-install, no re-torque is required after the initial torque set. The MLS Head Gaskets are designed specifically for the RHS® block and optimize coolant passages and cylinder sealing (RHS® recommends only using RHS® head gaskets with RHS® blocks).
Third, the LS Engine Main Cap Puller is specifically designed to fit LS engines. This sturdy tool makes the job of removing the doweled main caps quick, safe and easy. In one swift motion, caps are removed and held tightly so they don’t fall and become damaged – no prying, hammering or damaging dowels required.
Finally, Intake Spacer Kits are a must for all tall deck blocks. RHS® Intake Spacer Kits are CAD designed and CNC-billet machined to the most exacting tolerances to fit a 9.750`` deck height. A lightweight scalloped design provides rigidity and function without adding significant weight. Intake Spacer Kits include required hardware and gaskets and are available for all three cylinder styles: cathedral port LS1, rectangular runner LS3 and raised rectangular runner LS7.
All accessories, plugs, bolts and other service parts for RHS® LS Race Blocks are also available so that you can get the most out of your engine. For more information about the RHS™ LS Race

To help support grass roots circle track racers during the 2010 season, RHS® has increased its contingency program to include more racers
Throughout the 2010 racing season, RHS® will reward winning grass roots circle track racers in various sanctioning bodies and racing classes by giving away thousands of dollars worth of cash and product certificates in the form of contingency payments.
According to RHS® Product Manager Kevin Feeney, “RHS® increased our circle track sponsorship and contingency program in 2010 as a way to give back to the racers and the racing community who support and use our products, particularly in the current economy. As a company made up of racers, we understand how important this type of support is, and we offer a very competitive circle track contingency program in the performance aftermarket.”
The following sanctioning bodies will be included in the RHS® contingency program this season: American Modified Series, ASA (Midwest Tour), CRA, IMCA, Limaland Motorsports Park (UNOH), SMP (Speedweek), USCS (OWM), USCS (Weekly Racing Series), USMTS (National and Southern Series) and USRA. RHS® will also offer support for grass roots circle track racing with a USRA Modified Division title sponsorship of the Open Wheel Modified class during the 2010 season.
In order to be eligible for contingency payouts, racers must first register online at www.racecontingency.com. For more information about the RHS® 2010 grass roots circle track racing contingency program in 2010, call us at 1-877-776-4323, or visit us online at www.racingheadservice.com.

Airflow technology leader introduces a high performance GM LS engine block for radical street & all-out racing applications
GM LS engines have truly set a new standard for V8 performance and durability. However, there are limitations for the aftermarket shopper when it comes to finding a high performance replacement for the factory block. Aware of this dilemma, the research and development team at RHS® went to work designing and testing several different versions of GM LS engine blocks until they found the optimal solution for performance engine builders and racing enthusiasts.
The LS Race Block is designed for added clearance and mass customization. Available in both standard (9.240”) and tall (9.750”) deck heights with an extra-thick deck surface (.750”), this RHS® block features a raised cam centerline and priority main oiling via an oil galley that is shifted outboard to allow rod clearance for a much larger stroke (4.600”) while also minimizing windage in the crankcase. Using computer-aided design, the cylinder walls are Siamese cast with press-in spun cast iron liners. Cylinder liners are available in both standard deck (5.67”/5.87” – same as the LS7) and tall deck (5.94”/6.38”) lengths. Also featured is a 6-bolt head design with a full water jacket around each cylinder (based on the LS7 design).
For quality control assurance, RHS® performs a CT scan on each block (similar to a medical CAT scan) to maintain maximum casting precision and consistency. Combine all of these features with a superior finish quality, thanks to the RHS® patented Clean Cast Technology™, ultra-precise computer aided design and extra surface material to allow custom machining, and you’ve got a GM block that sets a new benchmark for LS horsepower, torque and durability.

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

Airflow technology leader extends Pro Elite™ series with new CNC-ported cylinder heads designed to maximize the performance of 360-434c.i. engines
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.
