can it be done? should it be done when you want a good tight seal?

where would you get O rings seals for 84.5mm cylinder bores?

Do you have any engine builders in your area? You should be able to pick some up from them.
You can do it. Everything will fit and your motor will run fine. BUT, if you are building a motor aggressive enough to need o-rings, then you probably need copper head gaskets as well. Check with SCE, they are very reasonable.
