Home Made header questions

[austincraig]

Greetings all,when building your own headers,is there a RULE to follow as to WHICH pipe coming from each cylinder HAS TO GO INTO a CERTAIN COLLECTOR LOCATION:TOP LEFT,BTM RIGHT,etc?Does" ANYTHING GOES "rule or should you GUESSTIMATE which HEAD/CYLINDER collector PIPE LENGTH to get EVERY PIPE LENGTH as close as possible to each other to get the "EQUAL PIPE " length that seems to be the BEST/ONLY way to make headers?Who has built there own headers and what head pipe did you put WHERE in the Collector and why.Thanks.
