Help your Coyote 5.0L engine breath easier with a set of CNC-ported heads from Justin’s Performance Center (JPC Racing). The CNC-ported heads are a joint-venture between JPC Racing and Rich Groh Racing (RGR) Engines. The two powerhouse companies are the driving force behind Team JPC and its numerous NMRA national championships as well as countless street performance achievements.
The Stage 1 CNC-ported heads increase flow 9-14% (depends on lift) and utilize OEM valves, valvesprings, and retainers. A five-angle valve job is standard with all Stage 1 CNC-ported heads. JPC and RGR completely disassemble the heads, including the valve guides, for maximum porting during the CNC process.
Turn around time is approximately one week as CNC castings are in stock but are assembled to order. Core exchange is required or a core charge is added to the final price. The forthcoming JPC Racing Stage 2 and Stage 3 CNC-ported heads have aftermarket over-sized valves, upgraded valvesprings, and will be available soon. Current retail price for Stage 1 CNC-ported heads is $1,595 with core exchange. JPC Racing offers wholesale pricing for performance companies.

All cylinder head flow testing was performed with a 92.2mm (3.630-inch) bore, which is the stock Coyote 5.0L bore size. RGR utilizes a Super-Flow 600 flow bench, 28 inches of water, and the exhaust ports were measured using a 1-3/4 inch pipe.
The JPC Coyote 5.0L cylinder heads have picked up to 30 rwhp in most combinations over un-ported heads.
