The question you posed kind of reveals that you have little or no experience with engines.
I strongly suggest that you spend the $9 US and download the service manual here:
Daewoo Lanos service manual
You will need the manual for measurement detail and you may be able to discern from the illustrations what you can expect for damage.
Most, if not all, of the valves are likely damaged, the valve guides could be affected, stem seals should always be replaced if the head has to come apart (it does), on higher-distance-used engines, I recommend measuring valve springs (you will need a micrometer and precision caliper on hand at the minimum), you may find pistons cracked at the top, bent connecting rods, damaged rod bearing inserts, damaged camshaft, damaged crankshaft bearing inserts, a complete upper end gasket set or rebuild gasket set (will have all).
The head itself could be damaged or even cracked.
Frankly, this is not a good '1st project' for anyone and if you do have no experience, you will need days of concentration to ensure you understand what is being done at each step, and you may find tools specified that aren't in the kitchen drawer and not useful for any other purpose or vehicle.
If you have a 2nd vehicle, this kind of DIY is great fun and will give you insight into the workings of an internal combustion engine.
If you need it daily, I don't recommend trying it at all.
If you have the time, it would be helpful to others with similar ills (and maybe some who have been delaying the replacement of the belt) if you would drop back to give us kind of a summary of the damage and approximate cost.
Thanks,

Thanks for taking the time to fill us in on your progress; good luck!

Thanks Freetek, as the obvious was stated--No I do not know anything about engines this is why I am not working on my car and hired a professional about this problem but I am trying to learn this one thing specifically so I don't get screwed!
Will do! 1st I hired a friend of my boss to just replace the timing belt that broke while it was not running but was not apparent at that time so I had a friend try and push start it (standard engine) and that was when the damage occured, being an interferance engine (I do know that much,lol)! So he had to take it to another machine shop and the parts for the Daewoo are hard to come by so I am not exactly sure what is being replaced other than the valves?!? Tried to call but lines were busy so I thought I would do my own research on it. Anyhow, the parts plus labor from the machine shop are $570. Then probably about $100-150 for my boss' friend to put it all together again. I trust the friend but not sure about the machine shop so we shall see in the end if I got screwed. But, honestly the car is a 2000 and this is the only repair other than routine maintenance and I consider myself quite lucky. I also have a 2000 isuzu Rodeo that I purchased about 3 years ago with high mileage and I have a feeling I am not going to be so lucky with it.
