Long Block work is as follows:
Full CNC blue print machining, (bore, deck, hone and line honed) – The Cylinder bores are blue print bored to a true 90 degrees from the crankshaft center line, prior to being diamond honed to within .0002 inch for precise piston to cylinder bore clearances. We main bore and line hone the crankshaft which is honed to precisely align the crankshaft in the engine block.
We bore the block back to the crankshaft center line and hone the block to RA13 finish. The piston diameter measured to the nearest .0001 inch matched to cylinder bores. The Cylinder block is surfaced to a finish of RA30 or lower, which meets the factory specification in both flatness and smoothness for the block to head sealing surface.
This is mandatory for proper sealing of a MLS Gasket.
Connecting Rods, New Damper and Flexplate for Automatic transmission. All Manual will be charged the appropriate charges and will be balanced to a stock flywheel we have in stock or you will need to send in your Aftermarket in first.

Common Issues With The 6.6L Duramax (and how we fix them)
Head Gaskets- This was the first Duramax engine to use the variable geometry vane turbo It was so rely problematic for the failures with head gaskets .While our business is engines, we also encourage the customers to fix the cooling issues and update the LLY with the larger later year model LBZ fan and radiator. But we will take care of our end. And that is why we make sure that all our Duramax engines come standard with headstuds. So you don’t blow a gasket.
