This 24v cylinder head is being prepped for installation on a fully built competition 6.7L Cummins short block. Industrial Injection’s competition head includes full CNC porting on the intake and exhaust, new valves, guides, performance valve springs, and fire ring head gasket grooves. The factory intake manifold is also machined off, leaving a flat milled surface that’s drilled and tapped to accept an aftermarket high-flow manifold.
