Hi there. I'm the farthest thing from an expert, but since no one else has answered yet, I'll give it a shot. I hope someone points out if I am wrong. We're just getting our first snake tomorrow (cape gopher), so I am not yet speaking from any direct personal experience. But I've been doing a lot of studying, trying to learn as much as possible about this new pet.
As a general rule, gophers tend to be much more easily excited and agitated when young. They mellow out some as they mature...but will always need consistent, gentle handling to remain tame and accustomed to human contact.
My first instinct is to say that heavy gloves and forced handling every day is not the way to go. I think that would stress the snake out even more.
Here's what I would do if I were in your shoes:
Check the snake's environment. Is it stressful? Are there lots of kids or noisy things going on around it? Lots of lights flashing on and off? (Like being too close to a TV?) I think it may do better in a calm, quiet environment.
Is the tank too warm? Sometimes if they are too hot they will be much more agitated than if they were comfortable.
Once I'm sure the environment is more soothing, I would leave the animal completely alone for a week or two, except for feeding...to allow some of that excess stress to bleed off. Then start very slowly allowing it to get used to me. (Or my daughter.) Three or four times a week with brief, gentle handling. Not every day. Only increasing the duration of handling as the snake accepts.
And one more tip that sounds very useful and I will employ with our own snake. Feed it in a separate container from its usual home. They are creatures of habit, and if it knows that your hand entering the cage means food is coming, then it will go into "hunting" mode every time it sees your hand. But if it is first moved into an entirely different place to find its food, it is much less likely to strike out at the "hand that feeds it."
Hopefully with time and much gentle patience, you'll have a somewhat more sociable pet.
Hope this helps some...
