SS + 1 as Matt says.... but,
1) The leaking new bearing seal so soon after replacement is a definate worry - how much is it leaking? Indeed a severely unbalanced flywheel could theoretically twist the end of the crankshaft, so clocking the flywheel is a good idea - I wish you luck as a bad result is going to hurt....

2) If you have muliple missfires on 4 out of 6 cylinders, surely it will also cause severe vibration at high revs - but do you get a power loss too? Changing the 4 coilpacks (or even moving two of them to the "good" cylinders to see if the problem swaps positions on the OBD tool) is a relatively cheap option.
Keep us informed.......
