Poston Headers

[machinegun]

Mine were pretty clean although I did just clean them up for the purpose of it. I loved mine and so far are runnign great on my car. Hope this helps.

I was just looking at my new set of Poston headers and thought. Wow, I thought these were the best you can buy. the welding on the inside of the pipes in the header flange is very very poor. It needs major work to not block the ports. I have built my own headers before and would never weld them this way and cause such a reversion problem as I see here. Has anyone else seen this? I was wondering if any of you have cleaned up the welds and if removing some of the weld to make them the way they should be caused any problems?

Thanks

musclecar neal,

I have Poston's passenger side header and just like you have indicated, the welding on the inside at the ports was quite rough. So before installing the header, I ported the inside welds and have not had any problems. Used a regular cheap exhaust header gasket (speckled aluminum looking thing with stock size ports) as a guide for a majority of the cleaning.

Before your start grinding, recommend bolting the gasket to the header and outlining the ports with a Sharpie marker. Each header will take about an hour to remove the rough stuff.

Good luck,
Richard
