I like the idea of trying to seat the valves insitu. I am really dreading dropping the engine again.

Neill,
A leak down test will tell you which of the valves is the culprit or maybe both. But doing the troubleshooting with the engine install in the car is quite a feat. If I were in your shoes, I would do the following:
1). Do a leak down test. Determine where the leak source is originating.
2). If one of the valves or both is the culprit, remove the valve’s springs and spin the valve against the seat. A very light spring compression (optional) will keep the valve up and against the cylinder head. Spin the valve using a hand drill. There could be some sort of debris or rust caught in between.
3). Test if the valve stem is straight and not binding. Do another leak down test. If the problem still persists.........you know what to do next?
4). I would drop the engine and do the troubleshooting with the motor mounted in an engine test stand similar to this set up.
Keep us posted and good luck.
