Id fill it back up how you had it. Especially if it ran smoother and quieter. If you are a little high and you are actually are a 1/4 past the full mark you'll be alright. That's not dangerously high. But chances are the oil level isn't actually that high anyways. You're all good man, fill it back up where you had it. High side 1/4 above full, low side 1/4 below full.
