Bulletproof Diesel stocks a selection of 6.0L heads retrofitted with hardened valve seats. Here, you can see the hardened seat under the open intake valve. The seat material Bulletproof Diesel used to achieve this upgrade is Stellite; a cobalt-chromium alloy that is known for its astounding hardness, toughness, and resistance to corrosion. Each of the engine's 24 valves received this upgrade.
