I think everything has been covered as far as the testing and if it was done correctly then you should have a great block.If you went over all the information with your machinist and are satisfied then get started on the build.
The only thing I question is not to use a short fill since your spending a lot of money on the block.The big issue we see is always on the tall fill and block not being clean inside and the cement not sealing against the block and cylinder walls or blocking water passages.But it's your decision as to what gets done.
Good luck with your build,and look forward to seeing you at the track.
