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.
