You gain HP or rather loose less...
But friction from compression ring will just show running the engine...not turning over by hand.
And what kind of power increase in % do you think it will gain for you ?
Older rings ain´t easier in any way...other way around since you need break-in which means the driver can fail doing it correct...and manufacturer gets a warranty claim.
Question is more where the money is best spent on a street engine.
