Big block heads on a small block headers

What headers are you running when you run big block cast iron heads on a small block?

What problems do you run into?

Thanks

Use the small block header. Width and height of block is what makes the difference in the headers. Otherwise the exhaust size and locations are the same on both bb and SB head castings.
