Stop in for a cup of coffee

Anything super special about these exhaust manifold bolts, or should I be able to just find them at a good hardware store?

I have the old ones, but the threads are junk

Can you chase the threads, or are they that bad.
A lot of bolts, tend to be counterfeit. Best to get them from an industrial supplier. Not Lowes or Home Depot.
