Jeep 4.0 stock casting "Competition" LS converted Cylinder heads. These heads are meticulously built from the ground up with all the upgrades and best parts such as: 2.02"/1.60" Stainless Steel 8mm valves, competition 5-angle valve job, fully hand ported and polished, beehive springs w/steel retainers and locks, upgraded Viton positive locking valve seals, custom machined spring seats for added cam lift capacity up to .600", machined guide holes for optional HD 3/8" pushrods, all fully assembled and ready to bolt on. **We recommend this style head for Strokers, Boosted applications, or 'Hot' upgraded 4.0/4.2 engines with upgraded cam, intake and header with increased rpm potential to reap the rewards. These heads depending on application and supporting mods will increase power levels from 25-75HP. ***(We also recommend a complimenting cam package, ported Intake, 60mm and larger throttle body, fueling upgrades(injectors/tuning/500CFM & up carb) and header collector size of 2.5" or bigger depending where you want your power band.) Undamaged CORE REQUIRED or a core charge of $200 will be applied.
