Yes go to Navistar/IH tell them it's exactly what it is a 7.3 non turbo IDI and you need a exhaust valve spring and keepers. There are 2 springs in the valve spring settup, an outer and inner which unless your cranking horrendous rpm will usually not allow piston valve contact but you may have a tinkleing noise from the engine.....loose spring/ valve parts.

We did not see you say that Malcolm.
Wait a minute, I guess we did.
Glow plugs, Motorcraft/Beru ZD 9 is the only one you want to install, the others are trouble.
