If you search, using the OEM donut gasket on aftermarket headers is pretty much the standard.

I dont see how the donut gasket would restrict air flow..

i have a j's and i used the OEM gasket, it fits around the outside of the header and the test pipe/cat then is angled so should direct seat when bolted together.
