This is a couple of inline six cylinder diesel cylinder heads that we rebuilt. The gray cylinder head is a Cummins diesel 5.9 liter 12-valve engine. The yellow cylinder head is a C15 Caterpillar L6 engine. We disassembled both heads and thermal cleaned them in our Bayco cleaning oven. We then blasted them in our Zero shotblaster before magnafluxing and pressure testing them for cracks. We then did a grind to the face of all the valves on our Sioux valve grinder and machined the valve seats on our Tobin-Arp seat-and-guide machine. Finally before assembling them we did a surface and square to their surfaces on our AMC mill surfacer.
