83 ATC 200 Gasket Kit - 200's interchangeable????

[turtlethepyro]

Whats going on fellow ATC'ers. I have a 83 ATC200 that i need to have a valve job done, and piston rings. On amazon and ebay i see listings for 200x's, 200s, 200m's and so on. My question is do all the 200's take the same top end gaskets? Or do i need to find a listing specific to an 83 ATC 200 (no s,m,x)

Thank you all in advance.

I believe that they should all be the same for the top end. It's the bottom end where you would probably run into the differences.
