For every integer $g\ge 2$ we construct 3-dimensional genus-$g$ 1-handlebodies smoothly embedded in $S^4$ with the same boundary, and which are defined by the same cut systems of their boundary, yet which are not isotopic rel. boundary via any locally flat isotopy even when their interiors are pushed into $B^5$. This proves a conjecture of Budney and Gabai for genus at least 2.Comment: 8 pages, 1 figure. Incorporated referee comments, streamlined paper, added citation to Hartman and discussion of boundary-parallel codimension-2 balls in high dimensions to the introductio
