The Industrial Injection street cylinder head for 2003–2007 Dodge 5.9L engines provides ported valve bowls and machined exhaust ports to improve flow for street-driven builds. These heads are suited for owners seeking better breathing and combustion sealing than a stock head while retaining streetable characteristics. They are intended for installation where moderate porting and intake milling have been performed.
