A quick way to find TDC, with your intake on I assume, is to pull your #1 plug, stick your finger in there, and bump the engine over either with another person or with a remote starter until your finger "pops". At that point, your piston should be at TDC, you can feel for it with a small screwdriver to check. Then check your rotor and see which direction it's pointing, mark it, that should be your #1.
