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:	62-74 B-BODY and 70-74 E-BODY • WILL NOT FIT 67-76 A-BODY applications!  This header absolutely will NOT fit in an A-body, with or without torsion bars.  Extensive modification required, too many interference issues to list!
2.  ENGINE SIZE:	440-RB, 413-426 WEDGE, INDY MAXX ALUMINUM BLOCK
3.  CYLINDER HEADS:	INDY-572-13 • 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.
4.  SPARK PLUGS:	ANGLED
5.  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. • UniSteer Performance:  Headers will not clear the UniSteer rack and pinion.
6.  ENGINE MOUNTS:	OEM, SCHUMACHER or EQUIVALENT
7.  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) • Applications with a 3-section throttle rod will require modification to the bell-crank & pivot shaft  (See illustration sheet #101)
8.  STANDARD TRANS:	YES • 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.
9.  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
10.  COLUMN SHIFT:	NO • DIY alternative:  Modify your shift linkage to achieve clearance. TTi does not make a linkage to satisfy this situation.
11.  PUSH BUTTON:	YES
12.  MANUAL STEERING:	YES
13.  POWER-STEERING:	YES
14.  AIR CONDITIONING:	YES
15.  STARTERS:	THE FOLLOWING STARTERS HAVE BEEN FIT-CHECKED WITH THESE HEADERS AND FOUND THERE TO BE NO CLEARANCE ISSUES... AUTO TRANS / STANDARD TRANS with a 10.5" flywheel (130-tooth ring gear)... • OEM or MINI STARTERS • Chrysler part no's:  R53005984, 56027702AC • Mopar Performance part no's:  P5249644AB, P5007860, P4286522 • PowerMaster Performance starter no's:  9513, 9523 (Catalog pg. 30)
16.  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.
17.  OIL FILTERS:	N/A
18.  OIL PANS:	OEM, MILODON • Milodon street & strip part no's:  30930, 30931, 31010 • Milodon road race part no's:  31580, 31581
19.  VALVE COVERS:	OEM, CAST ALUMINUM, STAMPED STEEL, FABRICATED ALUMINUM
