Potvin liked to use the steel 32 cores for his 425 Eliminator grinds - as his profile had a pretty "pointed tip" and he liked a steel core for the smaller base circles his 425 grind ended up with. Also, the thought was that the nose of the lobe wouldn't wear as much as with a cast core. In most original Potvin 425's the journals were ground to .010 under. In later years I also saw some cast core 425's with hardface overlay welds on the tips of the cast core lobes.

I've always been curious as to why the cam journals are turned .010 under on an Eliminator. What is the reason for this?
