If you can find one (and I don't know if they make one) go with the 2 pc. and center o-ring. Then go with the 1 pc. Do Not use the copper unless you have the cylinder o-ringed. It will leak, I know some use the dopper without the o-rings in the cylinder, but they just don't seal good without them. The o-rings mash into the soft copper to make the seal. Plummen is right! Again!

Wiseco one piece fibre gasket, fill the slot for the o ring with sealant.
Copper needs grooves and wire to seal.

Use the Wiseco one piece gasket. Be sure to modify the dampner blocks as shown in this link. Don't ask me how I know!
