The cleaning job you have done surely looks good, but I would not even try to start this engine if it was mine. Even if everything looks nice and shinny, there are all kind of residus on the lower part of the cylinder wall , side of pistons, rings and oil pan. You have also introduced a lot of debrits in the oil and water passages.
At this point, you have 2 solutions:
1) take the engine out, dismentle, clean or replace worn parts.
2) re-assemble everything without doing further work on it and sell the car to a non-friend.
