me neither tech. and that is one of the many reasons I asked this question in this forum... great minds.

Cat diesels are a great power plant - if you want to watch a lump of yellow iron all day.
Perhaps that was true 20 years ago. The c32 engines are a nightmare. They are too new for the Tech's to know anything about, and I believe they already discontinued them.

On another note, I had no real intentions of keeping these heads long term, just getting a vehicle running to get it outta the shop and running around more before I spend anymore time on it. When I get home, I'll pop the headers loose and take a looksie

thanks again,
Drew
