Building a high-performance 12-valve Cummins?
This complete kit from DCEC Cummins has all the goodies you need for a serious valve train upgrade.

It's designed for the 5.9L 12V engine found in Dodge trucks from 1989 to 1998.

You're getting a set of 12 heavy-duty 60lb valve springs, a full set of 191 exhaust valves, new valve cover gaskets and O-rings, valve stem seals, and the specialty tools you need to install it all—including a Tork Tool compressor and a 32-spline delivery valve socket.
This is a custom, performance-oriented kit that lets you rev higher and make more power reliably.

Part numbers include 3916691, 3902666, 3921640, and more.

Everything is brand new.

If you're building a high-RPM 12V, this kit is a solid foundation.
