Yes, ARP bolts require re-sizing, Thats why I wonder about Katech. How do they provide a stronger bolt (better clamping), would require more stretch because of higher tensile, yet don't require resizing?
Doesnt make sense to me.

To answer You're question the first design bolts have a smooth straight shaft that is a little narrower than the second design bolts and the first design bolts use an insert that goes into the rod and they are a little longer . The second design bolts are a little fatter with what looks a little similar to the Wave-Lock ARP bolts on the shaft and they are a little shorter overall and the threads are a little shorter than the threads on the first design . Personally I kinda like the ARP bolts because they not only are stronger but they are longer going all the way into the threads on the rod making the rod a little stronger at the big end . But the stock bolts are good safely to between 400-450 whp and 6200rpm's . Oh ya the first design bolts the diameter of the shaft is a little smaller than the threads and the second design the shaft is the same diameter as the threads .

I have always doubted that there is any real difference with the stock rod bolts from year to year. I bought my 98 Z28 with 71,000 miles, went through 3 different cams and bolt ons, and cranked it to 6800 with the last two cams for over 40,000 miles, and it blew a head gasket at 147,000 miles...bottom end was solid!

Only the 01+ cars have the stronger rod bolts because of the C5 Z06 having a higher redline and rev limiter (6750) while still having warranties to honor.
That said I tend to agree with moe above. Shoot there are 2 bolt LT1 guys who have been spinning their shortblocks to almost 7000, and they hold up for a reasonable amount of time. If those can, any LS1 certainly can survive 6800 just fine! I'd worry more about a good tune.
