Crossover pipe Gaskets?

[87GNcospg]

has anyone ever used doughnut style gaskets on the crossover pipe? i know it didnt come with any but has anyone had luck with using gaskets to keep the crossover sealed up? the circles on the headers and crossover look perfectly round but i would still like to use a gasket to keep them tight.
this is on a TTA.

I don't think you can use them...but, if they do make em I need em on my 86 that suckers crossover won't seal for nothing.

You cant fit a donut gasket in there because of the donut shape already on the header flange. All things being "correct" you don't need a gasket.
