Header Size
Big block Mopar’s love big headers and big carbs. If you build another set I would build them 2 1/8” - 2 1/4” primary about 32”-36” long tubes and 3 1/2” - 4” collector for the most power. This is if it’s a healthy 493.
We built a set of 2 3/8” primary 4 1/2” merge collector headers for my 572 and they made a huge difference. All the tubes are equal length also.
