What's up ht I have a set of arp rod bolts that I plan on using on my ls rods for a lsvtec build and my question is: must I have the big end of the rod honed? And if so would I use an oversized rod bearings?

 

You should have it checked (and probably resized) but you will not have to use oversize bearings unless your clearances on the rod journals of the crank require it.

(They should be able to make it round again without oversizing the journal of the rod)

So as long as your crank measures good you should be okay.
