What I now believe happened with my engine, was a couple of things. The first thing is the aftermarket chip I'm now running. It suppose to be good up to 8500 rpm. But, after 8500 rpm, there is no rev limiter or fuel map. When I missed my shift and took my car way beyond 8500 rpm I had no fuel. Detonation! And with the high revs, the high compression and slightly thinner cylinder walls might explain why the number 3 cylinder cracked and 6 out of 8 of the valve springs on the exhaust side came out of the retaining clips. Another theory behind the valve springs coming out is that my adjustable cam sprockets slipped. I'm going to stay on top of them a little better in the future.

Lesson learned: DON'T PUT THE CAR INTO 2nd GEAR DOING 80 or 90 mph!

The real lesson: Watch aftermarket chips. If they say no rev limiter ask the sales person if that means they have infinite memory for an infinite fuel map. If they have, they've solved all the worlds memory problems ;P So a good back up would be an ignition system like Crane or MSD which have adjustable rev limiters which would be much more kinder to your engine :(

Alright, sorry about the math lesson.
