Oil burn cloud on engine deceleration

Need help with the seals. I have 8 of each of the following. I have only done #1 and 8 but so far it looks like both exhaust and intake have the tall seal on them. How should I arrange my seals since I only have 8 tall 8 short?

The seals I have taken off so far look newer and with no damage and still playable. However they do have oil on the inside of the seal.
