Default Race header sizing

I'm getting ready to have another set of headers fabricated for my car and I wanted to get some knowledgeable opinions on header size. My current headers are stepped 2 1/16" to 2.25" primaries. The combination is in my signature below, but the engine is 541 CI, and I shift around 7800 rpm. HP is around 1050. Does anyone else have a similar combination, and what size headers are you running?
