cast iron headers

[Mondo]

I have long tube headers on my truck now and I don't like running the exhaust down below everything (it can't be bent above the first crossmember).
So I'm looking at shorty headers but would really prefer cast iron as they are quieter (getting old).
I've seen the Sanderson model and a nice custom ramhorn style. When looking at the Sanderson site it doesn't recommend this header for our trucks with smallblocks but they have it for bigblocks.. It seems their would be more room with a SB. Does anyone have a set on their small block
