1998.5-2002 24V NOTES:

These valves require 1.190" spring pocket. Some heads may have been machined wrong and be too small to fit these springs. A machine shop should be able to machine the pocket to fit.

These are the same springs we use on our Performance Series Cummins cylinder heads, the same one that is in our 1,700HP Mega!
