Who makes these headers??

[Mojoluv]

I have a set of small block A-body W2/W5 headers. These are 1 7/8" and are full under chassis. No tubes go out through the inner fender. They use adapter plates. I cant find any manufacturers markings on them anywhere. Just curious if anyone recognizes who makes these? Thanks...

Is that for the PCV on the collector?

this port is for a crankcase evacuation system - some sort of pcv, but more effective, used for racing - not in the grocery getter.

something like this:
