You Had to be There
I really don't see how a bolt that acts as a "spring" can can keep a head planted where it should be on a block in constant varying amounts of boost and cylinder pressure.
All bolts act as a "spring" when properly tightend or they would not provide the clamping force necessary to keep the pieces clamped together. The bolt load applied to the bolts when they are torqued is specified by the design engineer so that the bolt exerts the proper clamping force to prevent cylinder lift off during normal operation of the engine.
