Square Flange headers ID?

[PxTx]

I'm not too familiar with some of the older headers. I've got a guy on CL with these and I know the square header collector's are usually an indicator of things being an older design.

Can anyone tell me what these are?

I would say Appliance or Blackjack from the separate flanges on each primary tube.

BBC Headers that have those individual port flanges like that are a pain in the ass.

I'm with Mark on that one. When I had my speed shop (now in a past life it seems), we sold tons of gaskets for Appliance headers.....You can probably guess why <g>.

I'm pretty sure that my '68 Firebird had square flange headers on it when I bought the car in May of '68. I never had any problems with them and never did know what brand they were. They can weld up headers in a jig, but I wonder if they ever check to see what shape the headers take after they have been run through a few heat cycles. The collector can move quite a bit in relation to the car around it. The first headers we put on the Chevelle worked fine for a couple of days, then I couldn't get the transmission into reverse. The collector had moved enough to be interfering with the shift linkage on the transmission. It happens when any weldment is stress relieved.

You paid for what you got, cheap headers fitted cheap.
