Beware all that may find themselves in need of an upper seal kit for your first gen motor. Those of you that have had to buy one may know the kit comes with more seals than you need due to the fact the kit covers 91-98. Well the old kits came with both types of valve seals, but as of this year the kits will only come with the new style which will not work on our first gen heads. Just be ready to buy the ones you need from another source because Cummins Crosspoint swears the old seals are not to be had. I finally found some at O'reily's.
