Stock Exhaust Gaskets w/Headers?

I bought a set of remflex gaskets to use for reattaching my headers after my rebuild. As I was putting them on the header shifted and the gasket slid down and bent... ruining them (yeah, both sides). Very frustrating waste of money.

I do have a set of stock manifold gaskets and am wondering if I could use those or if I need to buy a different type of header gasket?
