You can get misfires for various reasons but usually on all cylinders can mean bent valves but still unsure as like I said multiple things can cause misfires.

Your rings aren't bad, the oil on the plugs is from the valve cover gasket, go to Honda and buy a new valve cover gasket kit, comes with the tube seals you need. Don't buy aftermarket gaskets, they suck and just leak over time. You need to pull that engine and overhaul it since it sounds like you just dropped it in without changing anything, t-belt, water pump and every seal should be changed on a JDM engine before swapping, if not it will just start leaking like crazy.

You should also change the distributor cap, rotor and wires with all OEM, could make your misfire go away.
