Fully assembled Ram 6.4L cylinder heads. They will fit vehicle years 2014-2020. Old cylinder heads were replaced with these brand new before determining the bottom end of the engine was bad and the whole engine needed to be replaced. These have less than 10 miles on them with all new hydraulic lifters and both R/L side yoke kits, intake and exhaust valves, valve seals, rocker arms, rocker shafts, and push rods. $2,500 for both, not willing to separate, serious inquiries only please.
