Here’s some pics of an International, or Navistar, Maxxforce diesel cylinder head we did a valve job & surface rebuild to. The original head had multiple cracks in most of the cylinders. We ended up exchanging the head with this one. This head has some dings on the surface which are due to some valves & valve seats failing. The dings are only cosmetic & will not affect the performance of the head in any way. This head was a much more cost effective option rather than cast welding the cracks in the original head.Motor Mission Machine & Radiator
