valve seal part number

[shocker998md]

So i called up gbodyparts and they dont have a set of valve seals in stock so i tried to find them at the local parts store. They are comming up with three different sizes that they could be. Does anybody have the part number that i need for replacing the valve seals on a set of regular plain jane 87gn heads?
