| The block fresh out of the hot tank-not too bad for a block that has been in storage for 10 years. Ultra Performance Machining removed all of the OEM freeze plugs to thoroughly clean the entire block.
| The block going through the surfacing machine. According to Ultra Performance Machining, having the machine's cutter head set to a high rpm combined with a slow travel rate will give us the desired mirror finish on the deck.
| The finished cylinder block deck surface should be as close to a mirror finish as possible when using a metal head gasket. The surface should be free of pits, lines, and scores and you should not feel any "snags" when you run your fingernails across it.
| Once the deck surface is machined, the torque plate is installed. The plate should be torqued to the final torque spec using proper spacers to simulate the actual cylinder head thickness. The head studs and head gasket should also be identical to the parts being used in the final assembly.
| Lubrication oil is fed as the boring/honing operation is being performed. The oil keeps the boring/honing bit and cylinder surface cool, preventing distortion of the cutting surface and prolonging the bit life.
