Some pics to help...Okay, I looked at both headers more closely. Both have a flat spot for creating your own opening and they both have a bung welded in them.
I'm not sure which header is the right and which is the left.
The header with the most bends and most tubes meeting near the collector, has a bung and flat spot right near the collector end.
The header that is mostly straight with one long straight pipe having the other three enter it, has a flat spot at the collector end and a bung at the opposite end in the front most tube next to the gasket.
Now a few questions.
• What is the best thing to use to seal the unused bung?
I used a pipe plug. Has survived hot temps so far
• What is the best place for the pyro sensor to go?
I originally had it mounted in the threaded fitting on the driver's side manifold. It hit the firewall when I reinstalled motor. Put in into the flat spot on that header
• Are there any OEM sensors that need to go into the new headers?
Backpressure sensor for motor is suposed to go into the passenger side header at the front
• Would there ever be a need for all 4 ports to be used?
You could add sensors for backpressure and egt probe for water injection.
alot of items are the same price via another vendor ...for example a dp chip cost the same from jody or itp.No website for em damn. well important question is are they cheaper to buy direct?
Excellent info! Thanks for the details and the pics. ostwhore2:Some pics to help...
Backpressure sensor line that I made after the stocker wouldn't fit properly.
I've never gotten a solid understanding if you need that sensor or not.
Hope that helps.
Something I remember, you will need to start all the bolts in there holes before setting the header tight to the head. This is required because some of them are too long to get past the pipe bends if you have the header all the way against the heads.Excellent info! Thanks for the details and the pics. ostwhore2:
Glad to be able to help
Is the pipe plug a ¼" NPT? Do you think these can be found in SS.
That is what I remember it being. Wouldn't see why not
Also, did you use SS fasteners, or the ones that came with the headers?
I used what David sent.
