Did you check all plugs? What abut wires? What about coils? What about injectors? Did you do a full compression test?

Didn't have time to check all the cylinders, but I will. I honestly never though about ignition components though

I have seen many exibit similiar concerns as yours which had valve issues, springs week, as well a few with failing valve seats. It is kinda difficult to diagnose valve seats which are in early stage of failure. I have found it best to pull the valve cover and make sure the rocker hasn't become tight which would indicate the seats are going away. hope thats not the case however I fear otherwise.
