Truth about roller cams.... BEFORE you make the switch......

Buy a new roller cam, and a new hardened steel gear...... no worries.
And along this line, I've read a 100 roller cam suggestions to people building motors, even newbies. And I've never read on this site where somebody said "be sure and buy that new hardened gear". Maybe it has, and maybe somebody asked and had it answered, but it's not the general remark when somebody suggest a roller cam. Thus, I'm sounding the horn!
