Header Selection Tip
Header selection isn't just about tube and collector size or even what type of coating you choose. It's also about ease of installation. How easy are they to install? Not all header flanges are easy to get a wrench on. Check fastener clearance with a simple closed end wrench. Closed ends will not always fit all bolts. Sometimes, you must use a box-end wrench. Wrench fit is the measure of a good header. Manufacturers don't always pay enough attention to installation issues. And with some, fit is really bad. Remember, headers call for header bolts, not peanut butter bolts from the hardware store. Header bolts have small heads for flange/tube clearance. Most header bolts have a 3/8-inch head.
