I'm not to sure of the specifics on replacing the valve seals. I think you need to remove the valves and use pliers or something to pull off the old seals and press on the new seals. As for the flywheel bolts, DO NOT use anything but bolts specifically meant for the flywheel! Those bolts have an extremly high torque spec and they stretch when you put them on. That's why they can't be reused.
