- (2) Flanges: 2 American made precision laser cut 3/8� thick header flanges to fit the Small Block Chrysler heads.
- Port Size: 1 3/4" or 1 7/8" Round Ports available
- (12) Mandrel Bends: We start off with an American made 304 stainless raw material, that is then bent in the U.S. for a genuine 304 .065 stainless bend. Our material forms better, welds better and last because it is a genuine 304 stainless.
- (12) Stainless Mandrel J Bends (6" and 12" staggered leg lengths)
- (2) 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. Just like our stainless bends, we start off with an American made 304 stainless and fabricate the industries finest collectors . 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)
- (2) 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.
- (5) Purge Caps: This simple, but effective method for back purging caps works great. Each kit includes 4 primary caps and one collector cap.
- (2) 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
(1/4 lb) Tig Filler Rod: Includes � lbs. package of filler rod
