I believe your car has an interference engine. What that means is that the valves will hit the tops of the pistons when the timing belt breaks while the engine is running. Many different bad things can happen because of this. Valves can break or bend, pistons can break, chips of metal can damage the cylinder bores, heads can crack. You get the picture. Without some more investigation you won’t know what happened, but something did.

Buying a remanufactured head may well be a good choice, but a compression test and a leak down test will give some useful info before the head is removed.

That is because some of the valves are bent. With this engine when the timing belt fails one or more pistons will strike the valves that are left open.

I don’t need a tire pressure gauge to tell me your tire is flat and I don’t need to perform a compression test to show why there is a dead cylinder after a timing belt failure, its going to be bad news.
