I have a header on the way and I want to get new hardware for it since stock is garbage. I wanted something with corrosion resistance. I'm looking at getting a set of APR-400-8013 studs, but that's only four and I don't know what else I'll need. Would two sets of those work? I know there's only two studs stock but I don't feel like tracking down the bolts because it took me half an hour just to find the studs lol. Please help a noob find parts for his old car!
