Exhaust manifold bolts?

Hi, does anyone know the part number for exhaust manifold bolts? Or a part number for aftermarket bolts? (not for headers, I want to keep the factory manifolds)

I think i have a small exhaust leak on the passenger side, and if I'm going to remove the manifolds to put gaskets in I definitely want to replace all the bolts too, I don't want to put old rusty bolts from -88 back in there...

They should be 3/6-16 Bolts. I would tap them, and put anti seize on the bolts before you thread them in.

I assume you meant 3/8-16 and not 3/6-16
