Back to the original question and assuming that you already invested in the headers and exhaust.
Even though Sanderson grinds the flanges and does not require anything more than sealant I run a copper gasket and good bolts. If your using the black oxide bolts that came with the headers try using ARP 6 point header bolts as they have a proper rolled thread. I keep the originals to mock up my next build.
I have used the stage 8 locking fastners and they work great once installed but it can be difficult getting the clips on if you have big hands. Breslin Performance in AZ made some locking bolts that used a center pin to lock a split bolt in place. I think they are out of business now and wish I had a bought a few extra sets.
I use 6 point ARP bolts since you often have to use an open end to get to the bolts inside a radius bend. If you run stainless bolts be sure to use anti-sieze on them and look for the high temp version that has copper in it. That goes for the Stage 8 products too.
I have two trucks with Sanderson headers and one car with orignal rams horns. At the end of the day its your truck enjoy it.
