Which crossover for Poston headers?

[b4black]

I picked up a set of new Poston's headers off ebay a while back. But they didn't come with a crossover. Will the stock 84/85 crossover fit? How about a 86/87?

It did come with copper gaskets - should I use those? Or go gasket-less?

Thanks!

Rich I think a 84/85 crossover will fit, heres a comparison with the one I got with my postons, the stock one is at the bottom.I dont think youll have sealing issues using the stock one since it has more area at the ends. (see pic 2)

I used a stock one when I had my Postons on the hot air car...worked fine.

Excellent. Great pictures. I think I've located a 85 crossover to try (I only have an '82 crossover at the moment)


Thanks!
