If you do replace them you'll need to aline hone the mains too. I left the old bolts in mine and turn 5k all day.

I agree, however, i replaced mine with studs and did not hone the mains and no problem so far. Mine runs 4900 rpms. I will hone them next rebuild.

Well, ok, but don't let Timminator find out. :D
I did put ARP in the rods though. ;)
