If you’re an engine builder, you know that boring and honing a block is an exact job requiring precise specifications. RHS Torque Plates replicate engine stresses and bore distortion, ensuring accurate boring and honing. RHS also offers its Multi-Layer Steel Head Gaskets for its line of engine blocks, specifically designed to maximize cooling and efficiency.

Official Press Release

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.
