The first think i Have to say is STOP DRIVING THE CAR. This is the exact
same item that resulted in my current engine rebuild (which resulted in my
current frame off restoration). As for fitting larger seats and valves, it
will only improve performance. Too bad you just replaced the valves though.
You will need to make sure that no part of the valve seat has broken off and
is lodged between the piston and the cylinder wall causing damage. Best of
Luck.
