Could someone (who KNOWS what they're talking about please and no one else) tell me which header would be best for low end torque. I've read in a Car Craft article and one other article that smaller, longer primaries are better for the low end. The Macs I know have smaller 1 5/8 primaries but aren't as long as the LTs. Which would give more low end power? I have LE1 ported heads and 220/226 cam. I am more concerned about 0-60 time than I am about 1/4 time and my car is a daily driver.
