Tooef, almost every domestic 90 degree pushrod V6 or V8 engine is indeed interference, and they do bend valves when the chain jumps...and I have seen BOATLOADS of the Buick-derived 3.8L do this around 150k miles. However usually by then the cars that the engine is bolted in are worth more in scrap so they get junked.
Just this week we had a Ford 5.0L V8 in an old Crown Vic towed in with a jumped chain. In their case, the plastic covering on the timing gear falls off and causes the chain to jump and bend the intake valves. Again, the car (a '90 model) is worthless and was hauled off to be crushed.
Honda makes bunches of interference engines...all the DOHC engines are (commonly found in Integras, CRVs, Civic Si, etc.). Had LOTS of Integra heads off for bent intake valves.
It is really silly and stupid to let a belt go beyond its normal PM schedule. And even then, once in a while they fail before that, but it is rare nowadays.
