Manually Altering Pixel Values in a DEM

Hi guys,

I have got a bit of an issue that has left me stumped, so I was hoping that you would be able to help out!
I am using a DEM in ArcHydro to establish the subcatchments of certain study points within my catchment. Since obtaining the DEM, peat blocks have been placed into the ditches to reinstate the peatland to a 'natural' drainage regime. The thing I am struggling with is manually 'raising' the pixel value of the specific pixels that now represent the block locations. I am trying to raise it to the same value as the max pixel value within a 9 radius. Is it possible to do this? I have shapefiles for every block location, but do not mind doing it one at a time if that is more feasible. I have tried using the neighbourhood toolset, but don't underdtand how I can tailor this to specific locations.

Thanks a lot
