Stock Manifolds
If time is on your side and you're cheap (like me!) soak them in vinegar. I bought gallons of vinegar (.99 ea), poured it in a big tupperware container and threw the manifolds in there, turning them over every week. Sat in there 4-5 weeks and came out looking nice, even freed up the rusted-shut heat-riser! I wire brushed them afterwards and coated them with Hirsch Hi-Temp Exhaust Paint.
