Someone school me on header size.

Good mention locomotion. I have the Hooker Super Comps @ 1-3/4 on my 5.9 in my B body. It’s an OE ‘03 that has only a rpm intake, 600 carb and a older vacuum advance distributor that was chrome box fired. Everyone told me I’d have a huge loss of torque. I felt ZERO difference! and they fit excellent. Zero denting! I alsjust have a set on my E body 4 spd with only minor work to dent a tube to clear the scatter sheild.

Best header for high performance small block E bodies, though I have not tried the tti headers yet. Though it have no reason to try. As a note, they also require a smiliar clearancing for the scatter shield.
