Can someone ID these headers?
Quality of welds looks very good. They have what seem to be adjustment ports for each cylinder? Would love to know more about them. Considering installing them (sans megaphones) on my car.
Thanks very much for any info.

Not sure but if the plugs are removable, they could be for EGT probe.

Probes make more sense....blind tuning tubes are usually bigger and longer.
They might also be for air injection...for emission. Bob

Those may be AR headers from a long-gone company. Feel inside the exhaust ports for an edge, if so, those are AR flanges.
The additional ports were added on after manufacture for EGT probes.

Thanks for the info...! Excuse my ignorance, but what does AR stand for?
Are these suitable for a street car if I use my current muffler? |
