Yeah leaked from day 1. Going to have fixed over the next two weekends. AB needs to do a much better job with the short block. Spray paint on the head surface, not sure why they even bothered to paint the block. I had my heads done locally and they look brand new. Aluminum block should have cleaned up fine if they did what the head guy did. Also area between the heads that has the chisel holes, was still like rough (like factory) and some bits just broke off. When the block was stripped they could have smoothed out this area too. They have a parts warranty, so we need to document everything. I think they will do the right thing - i.e. pay the guy I have doing the work , its just that after buying something new you just want it to work and not have to fix their mistake.
