quick question 200x

[Rawlins350x]

Looking on ebay I'm finding 83-85 valves and then 86-87 valves. just curious if they are the same before I fork out the extra bucks for the more pricey "86-87" valves?

according to part numbers they are not the same

My guess is each is specific to their own machine. If you ever saw the first gen 200X engine next to a second gen the differences between the two are huge.
