Help! I'm Confused!

I need a long bolt to take account of the extended serpentine pulley for my dry-sump pump. I've got a nice 10.9 high-tensile one (like the stock OEM grade) that's just the right length but will it be ok to use it????
How should I tighten it???? Same as the stock bolt????
Because it's longer and is bound to be slightly different physically, it's going to tighten up a bit differently isn't it????
I've heard of a few problems with the crank bolt on the LS1. What are you all doing? Loctite? OEM torque spec?
PLEASE HELP!!!! Especially if you have a dry-sump set up.
Thanks,
Tom.
