Except for when they eject the rear spark plugs, starve for oil at the back of the heads, and/or have their intake manifolds shatter.
I'd forgotten about that little intake problem.
Only heard of the intake shatter with nitrous, NEVER heard of the rear plugs blow out on a DOHC, and I've only heard of starving for oil at the back of the heads at 150+mph under load.
(This is from personal experience btw)
My friend had the intake blow apart in his stock 4.6 Cougar, so while not a common occurrence, it can happen.
