ISF Valve cover/Spark plug gaskets

I need to get the spark plug gaskets done on my ISF but I want to know what other seals to do at the same time. I've heard there's a few oil seals and the valve cover seals that I may as well do at the same time. IF anyone has all the part numbers or at least seal names I need to look for that would help a ton!

Thanks

Side note. I would highly recommend doing the passenger side first as for me it was the most challenging side. Also I would say to torque all the lower 10mm value cover bolts first as they are the hardest to get to. I'm a huge fan of taking on the most difficult things first so the rest is easyer.
