header tube size

Either size will work well on a 350. Don't fall into the "equal length" trap. Just buy a merge collector from Performance Welding. The larger header may want to be shorter on the primaries. If you don't buy a merge collector, consider buying or building a header that fires in rotation into the old style collector. But, the bottom line is, it's all theory until you get an ET slip........
