Default Which ARP rod bolts to use?

Stock bottom end, just wanna beef up the rod bolts to make sure I'm safe in revving a little higher (7k). Which ARP rod bolts should I get.

As always, please offer some info explaining your answer.

I would get Katech because they are made especialy as a replacement bolt.
ARPs are good on builds but as a stock replacement you can't beat the Katech (will not distort the out of round)

I'm not sure what that means. Aren't the ARP's built to replace stock bolts too? I mean, they have a part number that is FOR LS1's. And I've never heard of an ARP failure on a NA stock cubed engine (or any engine for that matter). Clue me in, if you don't care man. I'm not up to speed on the Katech's special qualities.

The katechs are designed to the exact same dimensions and head size as the stock bolts,so when you take the stocker out and put the katechs in,all you are changing is the strength,and not the shape or size of the bolt.This allows the katechs to simply be put in place of the stock bolts,without resizing of the bearings or checking clearances...Apparently with the ARP bolts,you need to check bearing clearances when simply changing them in..On a fresh motor it wouldnt matter as you would have to check bearing clearances anyway,katech or arp.

I have never heard of a failure from either bolts,but there may be an added risk..I do believe the katechs are slightly stronger too,but i dont think thats important.
