We rebuild light duty cylinder heads in house. As long as the crack isn’t into the deck surface we machine the crack out when counterboring for oversized hardened seats, no welding necessary. 6.2 and 6.5 headgasket failures are not exactly common unless they are abused or subjected to cylinder pressures beyond what the engineers designed them for (ie a turbo or two on a 6.2). Both the 6.2 and 6.5 are very reliable platforms if LEFT ALONE. If you want to make more HP in either engine then as the old saying goes… you pay to play. In my experience which includes many years of increasing the horspower on light duty diesels, why play with an inferior engine design like the 6.2 or 6.5 as it will never make the hp reliably that a Cummins, duramax or even a 7.3 power stroke will. Keith, I think it’s great that you are going to attempt to put twin turbos on your 6.2. I’m all about innovation and experimenting with new ideas. The problem is with the 6.2 and 6.5 many people and companies have “been there done that”. Sometimes it’s best to realize that you can’t polish a turd and accept what you have before you spend a bunch of time of money on an engine that will most likely disappoint you in the end.
