Hi Frank,

When the car is at idle the rpm is about 900-950. Enough to cause damage.
Usually 2 to 4 valves are bent, maybe no damage to the pistons.

The HG (Head Gasket) on a 25 year old 944 usually needs replacing at this point.

Get a cam/timing belt and try to get the timing marks aligned when you install it. You should feel resistance if the valves are bent.

If the PO did not keep up maintenance on the car, it is time to do the work.

GL
John
