HEADER FITMENT... • 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 •  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.  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, 493-572 CRATE, WORLD ALUMINUM BLOCK
3.  CYLINDER HEADS:	INDY-440-1 INDY-440SR EDELBROCK VICTOR* PROCOMP* STAGE-6* *If using Edelbrock Victor, Procomp or Stage-6 cylinder heads, clearance will be required to the passenger-side header.  When ordering, request modification and state cylinder heads.  Passenger-side engine block clearance part #SP004. •  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 •  If your cylinder heads require straight spark plugs, clearance will be required to clear straight plugs.  When ordering, request plug clearance for straight plugs.  Straight plug clearance part #SP002.
5.  FRONT SUSPENSION:	OEM or EQUIVALENT, with torsion bars / COILOVER, without torsion bars •  Coilover Suspensions:  Fit-checked with RMS Alterktion, Magnumforce XRT Tubular K-frame or Control Freak •  Headers will not clear UniSteer Performance 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 •  GM4L60E/GM4L65E Transmissions:  Modification will be required to the passenger-side header to clear these transmissions.  When ordering, request modification and state transmission model.  Passenger-side transmission clearance part #SP008.
8.  STANDARD TRANS:	YES •  Flywheel:  10.5" 130-tooth ring gear & 11" 143-tooth ring gear (11" Flywheel 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.
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... Chrysler part no's:  R53005984, 56027702AC Mopar Performance part no's:  P5249644AB, P5007860, P4286522 PowerMaster Performance XS torque starter no:  9523  •  Applications with an 11" flywheel (143-tooth ring gear) must use a RobbMc Performance starter #3005. •  Applications using Edelbrock Victor, Procomp or Stage 6 cylinder heads, must use a RobbMc Performance starter #3005.
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:	OEM
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
