Long tube header install

So i have all of my exhaust pieces now and i am just trying to make sure i have all my bases covered before i do the swap in the next few weeks. I have Hedman Tork-Stepped Long tubes, a prochamber, and flow master 40's. My only real question i have left to answer is, should i use the stock studs and nuts or buy header bolts. And if i should buy them does anyone have suggestions as to the best one, size, etc

Buy new header bolts.

I would suggest - Stage 8

Ive been using the stock bolts and have no problems. Not saying its not worth it to buy nice locking bolts but just that ive had no problems with mine. Im making well over 500 hp and actually my header cracked where the primaries are welded to the collector. So the bolts held up better than the header for some reason

Did you do your install with the motor in the car? I've read that you cant get the headers down over all the stock studs with the engine in or i would use the stock ones with no questions

You should check your motor mounts and exhaust supports if you broke the header.
You may have issues with the motor mounts letting the engine move to much or the ehaust hangers holding the exhaust in a bind.

Differences are:
"100% reliable, zero failures in more than 6,000,000 applications. Header fasteners absolutely, positively will not back out. Eliminates need to monitor and tighten bolts regularly.
Grade 8 aircraft quality bolts made in U.S.A. Duplex nickel plated
Manufacturer's Lifetime Warranty"

Plus they have the allen wrench center for tightening when you absolutely cannot get a wrench in to tighten the bolts.

My case was far from that i wish it was that simple but ended up that with my high boost and a ccrm fan relay that was bad i ended up with a small head gasket leak that gradually got worse. It eventually started blowing water through the exhaust like a typical head gasket failure causing my exhaust to heat and cool too rapidly and cracked right at the weld
