That's exactly what I was thinking, Gary. It seems to me like the 2" headers would suffice, and besides, I have straight angle plugs in my 452 heads, which appears to require some "customization" on the step headers but not on the 2" 440s.

You can play around with some header calculators to compare the output.
http://www.wallaceracing.com/Calculators.htm has a couple header calculators to try, for example.
