It's okay - we all start this process as novices and learn from those who have done before. TDC is when the intake and exhaust valve are both closed and the number 1 piston is all the way up in the cylinder. When you say, "... the exhaust and intake valves are even." how are you determining this? Did you remove the valve cover?

As a suggestion, you might reach out to someone in your area to literally walk you through this. There must be a club or a garage where you can meet someone and have them come to your house and help you with this. While not difficult (to someone who's timed a zillion engines) it's frustrating until mastered.

Good luck!
