Hmm... that sounds strange to me.
The VW 8 valve blocks are a non-interference design.
If the head was replaced, it wasn't because of a broken t-belt.
Actually, I am surprised the head was replaced at all... those 2.0 ABA engines are pretty bulletproof and are seldomly cracket open before 200,000mi.
If I had to wager on the durability of anything on that car it would be the engine... maybe it was overheated???
