What exactly do you mean by spark plug seals?

 

The DOHC motors have an O-ring like seal around between the valve cover and the head around the spark plug...is that what you're talking about? Your engine shouldn't have anything like that, as the spark plug hole is above the valve cover.

Just looked at my '96 legacy 2.2, and yep the spark plugs appear to go right into the heads above the valve covers, so I don't think there would be a spark plug hole seal.

 

However on '00OBW 2.5 sohc the spark plug holes do penetrate the valve cover and have seals that look like the ones in pic below.
