If I were you, I would find a set of used Clifford Performance headers on ebay. The Cliffies have 1 5/8" tubes, the Headman's have 1 1/2". With your sbc valves and porting, your build is all about making the engine breathe.

NOTE** Buy the SI valves that are made for that engine. That way you get the proper length, and the 1.94" and 1.60" you're looking for. $150 plus postage.
