As I wrote earlier, I cannot understand what you are trying to prove. The main difference between La-5FN and La-7 was a metal spar and this was the reason of the new designation. Otherwise it would have been called like La-5FNb or something like that.
Concerning Soviet hardware, I have some aircraft parts of various origin in my collection. Unfortunatelly it turned impossible for me to acquire a complete seat for La, but I am crossing fingers I will get it one day. So, I know what I am talking about, when I say that Soviet hardware was inferior. Frankly, it often looks so awful, the one does not want to touch it!
Thus said, such Soviet fighters like Spitfire or Kingcobra certainly were on par with Western aircraft, but Soviet designs were not. Soviet propaganda tried to prove otherwise and found some followers in kind of Pilawski, but the facts are undeniable. Both Kingcobras and Spitfires were in Soviet service in the early 1950s, long time after Soviet designs were phased out. Kingcobra, while tested against ultimate Yak-9P turned superior, still being much older design. It was mentioned on very this forum some time ago, but apparently you are not interested in facts, if you repeat what you wrote previously.
