STBB cup seals

[Psycho91]

I know for some stbb there is a valve spring length difference but is there a cup seal difference, these are the 2 cupseals I have on hand and ima guess one is spyder and the other is a clone of some sort, ima guess it came out of my mongoose

Other then the cup seal looking different I did notice the valve stems are different lengths

Will either work with any stbb stock valve or am I just gonna have to see which one works with what valves

Or maybe it's hammer specific? Is that one valve stem longer to compensate for the fish's shorter hammer or am I thinking to hard right now lol

If anything that long one is probably designed for a retaining pin that goes through the body and the other isn't?

Try and find out. I would put the longer one in and then look down the feedneck, see if the bolt has any gap you can see because that's where the valve will start opening
