HEADER FITMENT • Our headers were designed to fit with the engines located to the factory specifications.  If the engine is not located correctly in the chassis, the headers will not fit properly.  We strongly suggest you check your engine location prior to installation.  (Click here for the factory dimensions) • Due to various manufacturing designs, aftermarket parts, engine configurations, suspension combinations, etc... TTi cannot ensure headers and exhaust systems to fit all combinations.  However, we have done our best to accommodate both factory and aftermarket component combinations.  In some cases, slight modification or repositioning may be required on your part to clear the specific situation.

1.  PLATFORM:	67-76 A-BODY, 62-74 B-BODY and 70-74 E-BODY
2.  ENGINE SIZE / CYLINDER HEAD COMBINATIONS:     (Engine size & Cylinder head must be stated when ordering)
383-400 B-ENGINES:	383-400 B-ENGINES must use the following "RAISED-PORT" cylinder heads for these headers to fit the 383-400 B-engine application combination... B1BS SPORTSMAN BRODIX B1BS KOFFEL'S ORIGINAL B1 INDY-440-1 INDY-440SR • Applications using EDELBROCK VICTOR, PROCOMP or STAGE 6 cylinder heads, use 2.0 x 2-1/8" header #TTi400SR-218. • Cylinder Head Studs:  Head studs may be used on the Passenger-side, however, on the Drivers-side the header tubes will not clear the cylinder head studs below the #3, #5 and #7 cylinders.  We recommend ARP bolts for clearance in these areas.
440-RB ENGINES: 440, 413, 426-wedge, 493-572 crate	440-RB ENGINES must use OEM or EQUIVALENT cylinder heads with an angled spark plug design... FACTORY 915, 906, 452 BULLDOG INDY-EZ EDELBROCK E-STREET EDELBROCK PERFORMER RPM • Applications using EDELBROCK VICTOR, PROCOMP or STAGE 6 cylinder heads, use 2.0" header #TTi440-200. • Cylinder heads with a straight spark plug design, use 2.0" header #TTi440-200. • Cylinder Head Studs:  Head studs may be used on the Passenger-side, however, on the Drivers-side the header tubes will not clear the cylinder head studs below the #3, #5 and #7 cylinders.  We recommend ARP bolts for clearance in these areas.
3.  SPARK PLUGS:	383-400 B-ENGINES:  Headers clear STRAIGHT or ANGLED PLUGS 440-RB ENGINES:  Headers clear ANGLED PLUGS ONLY • If using B1BS Sportman, Brodix B1BS or Koffel's Original B1 cylinder heads, we recommended NGK & Accel plug wires for adequate clearance   NGK Spark Plugs  - 14mm thread, 19mm (3/4") reach, 5/8" (16mm) hex size. Street use:  part # BKR5E,BKR6E, BKR7E Race use:  part # R5671A-7, R5671A-8, R5671A-9, R5671A-10 ACCEL Spark Plug Wires - Extreme 9000 Ceramic Boot with straight or 90º plug ends.
4.  FRONT SUSPENSION:	OEM or EQUIVALENT with torsion bars COILOVER without torsion bars:  The following coilover systems have been fit-checked with these headers and found there to be no clearance issues...  RMS Alterktion, Magnumforce Tubular, Magnumforce Modular Transformer, Control Freak • Steering Linkage:  OEM with torsion bars or Rack & Pinion without torsion bars. • Steering note applies to 67-76 A-bodies & 62-65 B-bodies Only:  This header will not clear a Quick/Fast Ratio Pitman & Idler arm that is longer than the OEM arms.  Example; The Fast Ratio Pitman & Idler arms by Firm Feel, Inc. are 3/4" longer then stock.  DIY clearance can be achieved by dimpling the header tube(s), however, doing this modification will void your header and coating warranty. • UniSteer Performance:  Headers will not clear the UniSteer rack and pinion.
5.  ENGINE MOUNTS:	OEM, SCHUMACHER or EQUIVALENT • 67-76 A-body applications with a stock front suspension, using Edelbrock Victor, Procomp or Stage 6 cylinder heads, will require using a motor plate to locate the engine.
6.  AUTO TRANS:	YES • Floor Shift:  Some applications with an auto transmission may require the adjustable swivel & the lower rod to be re-positioned to clear the header collector, see illustration sheet #3703
7.  STANDARD TRANS:	YES • Flywheel:  10.5" 130-tooth ring gear & 11" 143-tooth ring gear. • 440 applications with an 11" flywheel 143-tooth ring gear must use a RobbMc Performance starter #3005. • Clutch Linkage:  OEM • Keisler/Tremec TKO-500/600 Transmissions:  It is imperative that the output-end of the tail shaft is in exactly the same position as the stock transmission output shaft for the headers to fit properly.
8.  FLOOR SHIFT:	YES • Auto Trans:  Some applications with an auto transmission may require the adjustable swivel & the lower rod to be re-positioned to clear the header collector, see illustration sheet #3703
9.  COLUMN SHIFT:	NO • DIY alternative:  Modify your shift linkage to achieve clearance. TTi does not make a linkage to satisfy this situation.
10.  PUSH BUTTON:	YES
11.  MANUAL STEERING:	YES • 67-76 A-bodies & 62-65 B-bodies Only / Steering:  This header will not clear a Quick/Fast Ratio Pitman & Idler arm that is longer than the OEM arms.  Example; The Fast Ratio Pitman & Idler arms by Firm Feel, Inc. are 3/4" longer then stock.  DIY clearance can be achieved by dimpling the header tube(s), however, doing this modification will void your header and coating warranty.  (This note pertains to 67-76 A-bodies & 62-65 B-bodies only.  Headers will fit 66-76 B-bodies & 70-74 E-body applications with Quick/Fast Ratio arms.)
12. POWER-STEERING:	A-BODY APPLICATIONS w/ Torsion bars:  NO (will not clear power-steering) B & E-BODY APPLICATIONS:  YES • 67-76 A-bodies & 62-65 B-bodies Only / Steering:  This header will not clear a Quick/Fast Ratio Pitman & Idler arm that is longer than the OEM arms.  Example; The Fast Ratio Pitman & Idler arms by Firm Feel, Inc. are 3/4" longer then stock.  DIY clearance can be achieved by dimpling the header tube(s), however, doing this modification will void your header and coating warranty.  (This note pertains to 67-76 A-bodies & 62-65 B-bodies only.  Headers will fit 66-76 B-bodies & 70-74 E-body applications with Quick/Fast Ratio arms.)
13. AIR CONDITIONING:	YES
14. STARTERS:	THE FOLLOWING STARTERS HAVE BEEN FIT-CHECKED WITH THESE HEADERS AND FOUND THERE TO BE NO CLEARANCE ISSUES... • Chrysler part no's:  R53005984, 56027702AC • Mopar Performance part no's:  P5249644AB, P5007860, P4286522 • PowerMaster Performance XS torque starter no:  9523  • 440 applications with an 11" flywheel 143-tooth ring gear must use a RobbMc Performance starter #3005.
15.  BELL HOUSING:	ALL • Lakewood Bellhousing scatter shield:  Modification is required to the passenger-side bell-housing.  A half moon shaped notch will need to be ground down approximately 1/4" deep to clear the header tube.
