I had Diesel Tech work on a Cummins ISX head for meWhen I got it back I started getting the cylinder head ready to installI noticed that the cam bearings looked bad so I stopedThe next day I went back to Diesel Tech and taked to SamHe said everything was ok to just use itI told him the bearings looked bad and Sam said thats how they came out of the box that they were fineThe new cam bearings had several scratches and gouges on bearing surfaces
