Sounds right.

A little flat or dent in the pipe will affect nothing.

Saw a set of either 1-7/8” or 2” headers on Joel Larkin’s ‘68 Firebird bracket car. One of the pipes closest to the steering box coming right out of the head was bashed in to about half its size. Kinda shocked when I saw that. Anyone who owns one of these cars knows how there’s almost no room there next to the steering box.

Didn’t stop him from running high-9s / low-10s with his ported #12 heads on a 400 (no stroker crank) with that car. He was running a Warrior intake topped by a Dominator carb, this was back in the mid-1990s.
