The exhaust definitely needs to be better seated but it sounds like you may be a tooth off on your cams. Remember that chains can stretch over time if you have access to a dial gauge or degree wheel that can help you get the cams sorted. Once those are in place a compression check will tell you if the valves are ok and after that you can go back to worrying the exhaust into place.
