on a ls1 block running ls6 heads, I was looking up ARP head bolt kits but it shows two different numbers.

http://arp.carshopinc.com/product_in...74869/134-3610
does anyone know the correct set for this?
the 3609 is a hex head bolt rated at 170,000 ,3610 is a twelve point head bolt rated at 185,000.
why would 3610 be less than 3609 then? The guy I talked to on the phone said something about then having staggered lengths in one set and the other set had all the same lengths.
If you read the date the 3610 says year models 2004 and up ls1/ls6. Whats different between them and say a 2001?
