I'm not sure where you get your information but cams do not mate in five minutes nor do rings seat that quickly. It's not a roller cam, it's a flat tappet. The manufacturer recomended 20 minutes at 2,000 rpm, then the inner springs were installed and ran again for the same duration. Ring material / cylinder finish often dictate the seating process. I was concerned enough to have my engine ran in on a dyno so I didn't have to worry about issues like leaks or partial dissassembly if the cam didn't break in properly and a wiped a lobe.
