NOT YET IN STOCK- SHIPMENTS BEGINNING EARLY 2025!

Our cast G3 Hemi Cylinder head incorporates several unique design features that offer  significantly improved performance at affordable prices.  The initial ports flow more  than 400 cfm on the intake and 270 cfm on the exhaust and we will achieve further  improvement prior to production.  The greatly increased bottom deck and top deck  thickness, results in far more rigid structure capable of high valve train loads and  significantly enhancing high cylinder pressure sealing.  The extended rocker stand and  added attachments significantly reduce unsupported length and reduce flex with stock  style single Int / Exh shafts.

•  Design incorporates insights from BES Racing Engines and many others with decades of racing, high 
performance engine development and manufacturing
•  All ports and chambers CNC machined
•  Initial ports flow more than 400 cfm on the intake and 270 cfm on the exhaust
•  Anticipate next iteration prior to production will be further improved
•  Extended rocker stand and added attachments to significantly reduce unsupported length and 
reduce flex with stock style single Int / Exh shafts.
•  Greatly increased bottom deck and top deck thickness, resulting in far more rigid structure capable 
    of high valve train loads and significantly enhancing high cylinder pressure sealing 
•  Standard configuration includes 2.18” steel Intake and 1.65” Exhaust valves and retainers
•  Cast, Machined, assembled and tested in the USA.
•  Sold as a pair.
