Timing Belts: Different Options

[Raptor]

I don't see a problem running the kevlar belt, I would only run it for the potential added saftey, I wouldn't try to go longer intervals between changes with it. That would be the biggest danger by running one I would think. Too much confidence in it and you could end up with those bent valves you were referring too.

It might be a really wise choice if you are running a lot of spring pressure and an agressive cam as well, the factory timing belt was not designed with those considerations in mind.
