I wouldn't do it just on the off chance of taking a hit because you scared the snake. I've been bitten by several different species of snake, all non venomous mind you, and pythons hurt the worst out of all of them. That being said my ball has never bitten me and there are times he will rest his head on my fingers or let me lift his head to look at his heat pits, eyes, nostrils, etc. and he doesn't care. Then there are times when he will snap back and get defensive. I just wouldn't do it personally because I would be worried about stressing my snake or getting bit.
