2-1/8” “LOW DECK STEP” HEADERS
for INDY and BRODIX raised port heads
2” O.D. primary tubes, 2-1/8” secondary tubes with 3½” collectors
 Designed to fit 1967-1976 A-body, 1962-1974 B-body and 1970-1974 E-body applications with 383/400
   low-deck engines with Indy or Brodix B1BS cylinder heads
 Clears Automatic or Standard Transmission
  Standard Trans:  Must use a hydraulic clutch actuator or modify the Z-bar as required to clear the header
      tube
Clears Floor Shift only
 Clears Manual or Power Steering on B&E-body applications
   A-body applications:  Manual steering only 
Must use listed Chrysler high torque mini starters only (Part no’s: R53005984, 56027702AC, P5249644AB,
   P5007860)
  TTI will not guarantee fit if using starters other than listed
 Will not clear large stock stick shift bell housing / Lakewood scatter shield bell housing
  With slight modification to the bell housing on the passenger-side, clearance can be achieved - A half    
       moon shape notch will need to be ground down approximately ¼” deep to clear the header tube.
 Clears 11” 143 tooth flywheel
 Clears angled spark plugs (Indy cylinder heads)
   For adequate spark plug clearance when using Brodix B1BS cylinder heads, NGK spark plugs with 5/8”  
       hex and 3/4” reach are required.  These spark plugs are 2” long from the base of the threads to the tip
       of the plug and will clear the header tubes.  NGK recommends: BKR5E thru BKR7E for street use and
       R5671A-7 thru R5671A-10 for racing.
   A plug wrench designed by TTI is available for removal and tightening of the spark plugs on the B1BS
      cylinder heads - Plug wrench sold separately (see Misc. parts listed below)
 This header was designed using Accel Extreme #9000 wire set (ceramic coating) because of the close
   proximity of the header tubes.  Accel part no. 9001 is highly recommended.
 Clears all cast aluminum valve covers
 Fits with Schumacher engine mounts or equivalent
 Recommend motor plate or elephant ears on A-body applications / Stock mounts for B&E-body applications
 Clears stock steering linkage
   Will not clear the quick-ratio extended length pitman arm and idler arm
A-body applications only:
“Position of engine is extremely critical”  
TTI recommends moving the engine back 3/16” for additional clearance of stock manual steering box, pitman arm and idler arm.  The (3) mounting holes in the steering box can be elongated to allow the steering box to be moved outboard for additional 1/8” clearance of the header tubes.
