[Gregski]

here I am comparing the new round port exhaust gaskets (top) with the oval ones (bottom) that came with the Flowtech headers.

I think the oval ones would have been way too tall to cover the E-Street heads flat bottom D shaped ports, but these round ones may just work.

the sharpie outlines the difference, note the top gasket is wavy and not flat so it seems like its off the pen mark, just letting you know
