Is there much size difference in 330 cc and 420 cc? Thinking of a revision. (photos)

hello louisa12 It’s important to know what size bra you currently wear. Is it a 32,
34, 36 bra, and, of course, the cup size? The strap size is important to
know because that affects the diameter of the cup and subsequently the
diameter of the breast implant that we choose. We also need to know your
height, your weight, and it’s helpful to know your dress size as well.
In addition, it would be very helpful if you include photos of
yourself. A front view, a side view, and a three-quarter view are most
helpful. This will let us see if there are any breast asymmetries, if
the breasts are narrow, if the breasts are wide, what your chest wall
looks.

Hello,Modern understanding of best practices suggests implants should be sub pectoral to minimize the risk of bacterial contamination. You appear to have the classic star gazing nipples so often gotten from a lollypop lift. You will likely need conversion to an anchor incision, and replacement of implants to under the muscle.  Issues regarding size of implant can be determined by in office sizing.  If your surgeon isn't an ABPS certified/ASAPS member surgeon who specializes in revision breast surgery, you should get a second opinion from a few who are. Best of luck!
