Exhaust manifold 302efi

[westcott]

Here the RH or passenger side of my foot boxes,there are some 20mm space between headers and factory heat shield.

On the LH or drivers side the headers (#6 tube) are 1-2 mm away from the factory heat shield. The edge protecting strip melted during the run in because i had the engine timing a bit late.

My headers are BBK stainless, 1621SJS, titanium matt coated, for use with EFI.

You mean JBA, not BBK, right Uwe [] ?

William, photo posting instructions HERE, and in my post of today(19th May) there is a hint on how to remove the line of code that appears before the photos above.
   Happy photo posting! Nik.

Yep..JBA, not BBK.

Oh yeah ! Really tight, indeed ! What is the material of the panel shied added ? No heat problem ? Or burned feet [] ?
   
   Ps : many thanks for this fast answer !
   

   The heat shield is KoolMat = NASA Thermal Protection System (TPS) materials developed by Rockwell Space Systems (now Boeing North America).  Still warm... but no burned feet!

   Yes, the air pump was removed and the remaining plumbing was capped.

We managed to use 1 3/4" tube as opposed to 1 5/8" giving better outflow. The origional stuff is certainly restrictive and if you get a chance to change / convert it is a worthwhile upgrade.

Nice, it does the trick and looks pretty good.
   Good suggestion for my planned complete exhaust rework during the next winter.
