I haven't been inside this motor but did you mark the position of the chain and sprocket(S) when you the cams. I am assuming that there are timing marks on bearing caps to the front and the cam base. Obviously, everything should line up at TDC so then it comes down to possibly having slack in the chain if not marked prior to removal.
