RHS® is introducing the latest addition to their brand new line of LS application cylinder heads
This is the aftermarket’s only high performance LS7 head with a raised intake runner design specifically engineered to accommodate production and aftermarket LS7 intake manifolds and valve train setups. The 12° valve angle (flatter piston to valve angle) and unique .220″ raised intake runners provide a better line of sight into the cylinders and allow for an improved short turn. In addition, the custom CNC-machined runners optimize volume, atomization and velocity.
The 355T6 aerospace-grade aluminum alloy heads also feature the popular LS 6-bolt head design that makes them compatible with both the RHS® LS Race and GM LSX Blocks. This design also increases clamping capacity to improve cylinder head gasket retention on high horsepower and boosted applications. All of this, with the addition of a .750″ thick deck surface, increases the integrity in high cylinder pressure applications.
A reinforced solid rocker rail with extra bolts was engineered for shaft mount rockers to provide increased rigidity and valve train stability, while the raised .400″ valve cover rails provide clearance for aftermarket rocker systems. And finally, the raised runner and rolled valve angle increase overall flow capability. These features, coupled with an improved water jacket design, make this an ideal head for both small and large cubic inch, hardcore street applications.
12° Valve angle & .220″ raised intake runner over stock LS7 provide better line of sight into cylinders and short turn

The latest Pro Action™ Cylinder Heads from RHS® are affordable LS-style heads that save you the time and expense of having your new heads CNC or hand-ported. These LS cathedral port heads combine race-proven head design and Clean Cast Technology™ to create “as cast” ports that flow like they’ve already been ported.
RHS® Pro Action™ Cathedral Port Aluminum Cylinder Heads for LS Applications are engineered with highly efficient combustion chambers that increase power and torque by improving airflow and flame propagation (the spreading of flames in a combustible environment) while multi-angle intake and radiused exhaust seats even further improve airflow. Their durable 355T6 aerospace-grade aluminum alloy construction is lightweight and increases cylinder head life and strength while high capacity water jackets generate greater thermal conductivity for cooler, more efficient engine operation.
The new Pro Action™ Cathedral Port Aluminum Cylinder Heads for LS Applications are available in three versions: as cast P-Port with no valve job; as cast 62cc combustion chamber with 2.02″/1.600″ valves, 205cc runners; and as cast 62cc combustion chamber with 2.050″/1.600″valves, 225cc runners. Stock valve angles and centers, drilled and tapped accessory holes, and stock port locations make these heads compatible with stock applications. However, added material at the top of each head allows for upgraded valve train components, making these cathedral port heads perfect for use in everything from mild street to all-out race applications.
Part # Description Runner Chamber Valve Size In. Ex.
54301 LS Cathedral Port 205cc 62cc 2.020″ 1.600″
54302 LS Cathedral Port 225cc 62cc 2.050″ 1.600″
Features & Benefits:
Clean Cast Technology™ creates as cast ports that flow as well as ported heads
Affordable bolt-on LS performance upgrade ready for use right out of the box in mild street to all-out race applications
Combustion chambers improve airflow and flame propagation to increase power & torque
Multi-angle intake and radiused exhaust seats improve airflow
355T6 aluminum alloy is lightweight and increases life and strength
High capacity water jackets generate greater thermal conductivity for cooler, more effective operation
Stock valve angles work with both stock and upgraded valve train components
MR Marine in Spring Lake, MI uses our EZ-EFI tunnel ram kits to convert twin big block chevy mercruiser engines to fuel injection. According to Mark, the install was straightfoward and trouble free. (it looks to me as if you’d have to stand on your head for a few hours, but Mark doesn’t seem to mind) Setup and tuning was straightforward and very effective. Start up was immediate. Our kits use Edelbrock Pro-Flow tunnel rams and throttle bodies, and FAST EZ-EFI controllers and electronics for excellent power and reliabilty.
The boat owner has been very pleased, fuel economy has significantly improved over the Mercruiser carb setup, and throttle response and mid range torque are much improved as well. Definitely a plus when getting a big boat moving. In fact, the owner of the boat originally ordered a single system to compare the fuel consumption and power for an entire season before purchasing the second kit. He was so pleased with the result, he ordered the second kit in about a month!! Congrats to MR Marine on a super clean install and a happy customer. Great job guys.
Leave it to Competition Components to put together a complete tunnel ram kit using FAST’s EZ-EFI fuel injection unit. We select the best components from individual manufacturers to assemble a great kit. Includes everything you need except for fuel lines!

We have added our entire line of Buick Cams to the site, both in hydraulics as well as solids. One of our flat tappet cams was # 1 Qualifier at the Norwalk Buick day both in 2009, and 2010. Nearly half the field both years had custom cams from us. Put our hard work to use in your Buick. Complete Listing here. These cams work great with Iron heads, Edelbrock heads both stock and ported as well as TA’s stage 2 heads. In addition, custom cam orders are encouraged. Also available through Finishline Motorsports. We do cams for v6’s, nailheads and 350’s too!
