Best Small block Headers?

Just a bit of info correction.

tti headers that 95+% of the engines out there can use a 1 5/8-1 3/4 step headers.

You need something really stout to justify a 1 7/8" header. And when you do and max power is the goal, there are other brands that work better.

The two choices for most people are the Dougs or tti step headers.
