Header building

Are there important dos and don'ts when building them?

Header builders seem to be a dying breed around Ohio, so we may have to try it ourselves.

I build my own headers; I use a program called pipemax to design them for size and length. the program also can be used to build step headers. To answer your question when building a set to fit in an engine compartment and maintain equal length is pretty hard. Getting access for plugs and starter is just as important. On a dyno not sure what the loss would be on different lengths, but I seldom see any factory-built headers that are even close. I am a big believer in step headers and have seen gains on the dyno.
