I don't think you have anything to worry about as long as your snake's eating (I know I haven't been keeping these guys that long, but I've never had a Gopher refuse a meal) and you're maintaining proper temps. I too have an '06 Pacific Gopher snake (WC W. Lancaster, CA, southern tip of its range)). In the 2 mos I've had it, the snake has shed only once. I would advise keeping a record of sheds & feedings. Just curious what's your snake's temperment like? I'd gone several years w/out encounterng a fiesty Gopher snake, and was beginning to think that tales of them, despite what my herping buddies told me, were hogwash --- til I got my little W. Lancaster, CA Pacific... Fiesty little booger. Good luck.
