What makes our header build kits the choice of top fabricators?

Included are:

• Flanges: (8) American made precision laser cut 3/8" thick header flanges to fit the Chevrolet Performance LSX-DR Cylinder Heads
• 3/8" Thick Flange Port Size Options: 2" Round Port Only
• Mandrel Bends: We supply (12) 180 degree J bends. Our J bends come with a 6" & a 12" leg. For most header builds, this extra leg length mean you won't need to buy any straight tubing.
• 4 into 1 Collectors: From there we supply a precision formed 4 into 1 collector or a set of our optional super high flow slip on merge collectors with 4 sets of collector tabs.
• We offer these header kits with 3 different collector options:
• Formed weld on collectors (Collector stars included)
• Slip on merge collectors with a straight exit (Collector tabs included)
• Slip on merge collectors with a transitional exit (Collector tabs included)
• Collector stars: A simple part that really helps speed up the fab process. Used as a weld in block off between the 4 tubes before welding the collector on, these are precision laser cut for a perfect fit between your specific primary tubes.
• Purge Caps: This simple, but effective method for back purging caps works great. Each kit includes 4 primary caps and one collector cap.
• O2 bungs: Each header builder kit includes 2 weld on O2 bungs. Precision machined in the U.S. from 304 stainless billet, these bungs weld beautifully, not like a cast bung
• Tig Filler Rod: Includes 1/4 lbs. package of filler rod Be sure to check out our Facebook, Instagram, and YouTube channels for continuous updates on customer projects, as well as how-to videos and information about our extensive product lineup
