Bump...
These would make nice high end power. If you installed the Titanium Hayabusa race valve springs you would never have a valve float not even with a money shift. The R&D on the Busa springs was amazing, they were stable at 25,000rpm per Metric Mechanic and I was the first to Road test them with similar cams you are selling. The cam profile has more duration which is the time a valve is open, the more duration you can run stable the more time you cylinder has to fill or empty it's combustion charge.
I give these cams a thumbs up.
