Yep, if you are deciding, use a little common sense and look at your checkbook balance. If it's a small cam Teen with a 4 barrel, headers really aren't needed. A basically stock 340, I wouldn't. I would just use the HP manifolds and rock on. You could still run it down the drag strip for fun. Of course, if it turns out to be a dedicated drag car, then it get's headers. Just a little common sense. I'm more conservative, I have no need to burn the tires off for a city block and 6 horsepower won't make much difference.
