Unfortunately, we have no idea what engines were used in what races or practice sessions apart from hearsay from the teams. The FIA publishes nothing other than when a driver changes an engine. Teams are not going to reveal what could be a competitive advantage and it gives the opportunity for a certain amount of misinformation.
All we do know is that Alonso's engine situation is probably more marginal than anyone else's, and on a circuit where his best bet is to maximise straight line performance there is probably little he or Ferrari can do other than finish.
