The OE bolts are TTY (torque to yield) meaning they were designed to stretch to obtain maximum clamping ability. What happens is they tend to weaken, and continue to stretch when cylinder pressures are high, causing the heads to lift off the block and blowing combustion chamber gases into the cooling system-adding a tuner only exacerbates the situation.
