In all my years at a dealer I never saw original plugs blow out, nor plugs my crew installed. Proper torque seems to be the key. Removing the 3v plugs wasn't a problem after the guys figured it out. They'd run the engine till warm, shut it down and replace all one side, warm it up again and do the other side. The V10's had a higher torque peak RPM than the 5.4 V8 so the customers with 4.10 or 4.30 gears liked them and had good luck, the guys who had 3.73 gears complained about lack of power and often had transmission failures because they were always shifting. Nobody with a V10 bragged about gas mileage but you can buy a lot of gas for the price of head gaskets on a 6.0 or 6.4 diesel. And V10's sound cool.
