Re: Headder Questions
Here is a link that has a header sizing chart. According to the chart a 350 making around 450 HP should have 1-3/4" primaries.

Re: Headder Questions
thanks for the link and the suggestion i think i might go with 1 5/8 primaries instead. another question will regular sbc headers fit vortec heads with no clearence issues?
