Re-Use bolts
True.
The stock GM bolts are torque to yield. Once you install them, you angle torque them to get final stretch. Once they are stretched, you cannot re-stretch them.
Get ARP bolts or be a baller and get ARP studs.

If you still have stock manifolds replace the bolts it's cheap cya insurance. I chunk them when we do them at work had a few here and there break off after pulling the heads while re torquing them

arp hardware is worth its weight in gold - one of the best investments you can make if you plan on doing any kind of work, be it maintenance or mods.
unless you're going to be rebuilding the shortblock though, I would stick with arp bolts vs. the studs. the studs load the block differently and could potentially alter your bore shape. most competent machine shops will ask you for the hardware you'll be using in the build and do the machine work with those to compensate.

That kit from summit is okay, but it comes with a lot of gaskets that don't need to be replaced. For example the valve cover gaskets and intake gaskets can be reused. The manifold/header gaskets can also be reused if they are undamaged and in good condition.
You want the earlier style bolts if you have a pre-2004 LS1.

The GM MLS gaskets seal up the best.

So the bolts in the kit aren't the right ones, I'm pretty much going new with everything, but I didn't know you couldnt reuse the bolts

The summit kit doesn't list early vs. later LS1; although, the photo shows 3 different length bolts which is correct (assuming the photo is what you are really getting). I've ordered from Texas Speed many times and trust them. Besides, you'll save a few bucks.
