OPTIONAL HEADER ENHANCEMENT KIT

While exhaust headers significantly improve your Bronco’s exhaust system, they aren't without their setbacks. Header bolts are prone to loosening, which often leads to a failing gasket and the resultant  annoying ticking noise. Additionally, the risk of burnt plug wires can cause misfires negatively impacting engine performance. These issues might make you question the benefits of headers, which are primarily power, performance, and fuel efficiency improvements. However, by incorporating a few additional components, these common problems can be mitigated, allowing you to enjoy the advantages of headers without the associated hassles. Our complete header enhancement kit will provide you with these additional components in one simplified part number. 

  1. Stage 8 Locking Header Bolts: These specialized bolts prevent loosening, thereby extending the life of your gaskets.

  2. Remflex Header Gaskets: Featuring a 100% flexible graphite construction, Remflex gaskets can withstand temperatures up to 3,000°F, significantly exceeding typical exhaust system temperatures, and ensuring a durable, burnout-resistant seal.

  3. Plug Boot Protectors: Protect your spark plug wires from heat damage with these protectors, which prevent misfires and ensure efficient spark delivery.

TECHNICAL NOTES

  • Not compatible with 3 or 4 port injector tubes: Please note that our headers are not compatible with 302 engines equipped with 3 or 4 port air injector tubes. These were sometimes found on 74-75 Ford Broncos as part of the emissions system. However, they can be modified to fit by grinding the header flange for clearance.

  • Not compatible with Ford GT40P heads: Our headers are not designed for use with Ford 5.0L "GT40P" heads found on 1997 & newer Ford Explorer and Mercery Mountaineer SUV's. 

  • No modification of smog system required: Our Pro Flow early Bronco headers do not require any modifications to the smog system that would render it operational. Existing smog systems should always stay intact. We recommend consulting local laws and regulations before ordering or installation.

Used these headers on a customer's 1975 Bronco with a 351W, Edlebrock heads, 5 speed, 2" body lift and FiTech. Fit with plenty of clearance, didn't bake the plug wires and ran cooler over all. These shorty headers with ceramic coating are the only way to go.

good looking headers which appear to be a quality product, one thing i believe you could improve on is a list of possible fitment issues
