Type: Cylinder Heads
Vendor: RHS

Description:

Pricing is per pair. 

At Borowski Race Engines, these RHS LS3 heads with our CNC port work go on most of our GM 6.0L block builds. 

THE HEADS IN THIS AD DO NOT INCLUDE ANY MACHINING.  PLEASE CLICK HERE  FOR OUR CNC PORTED RHS HEADS.

We like RHS LS3 heads for their price, performance and quality in their 4-bolt head category and we have a great CNC porting program for them.  Out of the box, they outflow GM LS3 heads.  They also outflow the GM heads after we have CNC ported both types.

RHS Pro Action™ GM LS3 Rectangle Port Aluminum Cylinder Heads have the same architecture as factory heads - all stock components will fit without issue.  They are made with premium materials and we have found that they show less core shift than other brands.  This allows us to run our CNC porting with totally consistent results. 

You can order these bare or complete.  The complete heads come standard with COMP Cams high performance spring kit and valves.  These are avalable either assembled or unassembled.  Custom Borowski spring kits and valves are also available. 

Because we use a lot of these heads ourselves, they are normally in inventory and available for immediate shipment.

Make sure you watch the video below to see the CNC ported RHS heads getting machined and running on the dyno. 

Think you might want to use the same CNC ported heads, fully assembled, as were on the engine in the video?  Click here.

Call us at 815-725-2727 with any questions or to place your order.
