Wait, was he running a 7000rpm rev limit on a Prius engine?
You shouldn't swap the non-Prius cams into a Prius, because the connecting rods are not meant for a 7000rpm limit. They made the connecting rods thinner on the Prius.
What you want is the Prius pistons in a normal 1NZ. A slightly different grind on the 1NZ cams might be desirable. Supposedly the 1NZ rods and valves can go over 7000rpm easily without modification (MR2 Spyder 1NZ swap guy had been running it at 8000 with a turbo).
Actually I don't even think that's a good idea, because it's a lot of effort for miniscule gain. I would just shave the head a little and slap on a supercharger if a stock 1NZ's power doesn't suit your taste.
