Well you did put it in the wrong section. And unless you are building a full on race motor stock hardware is fine for the mains.

no offense but topics like this are routinely covered here so that probably the reason for no responses. but to answer the question no, any other fastener than stock should be align honed. the arps have a higher clamping force than a stock bolt and will therefore distort the bore. the way to do it would be to install the arps then take it to the shop so they can get the bores back in spec, if your going with arp mains then i assume your upgrading the rod bolts also? if thats the case the arp rod bolt must be fitted and honed in a similar fashion
