I've never used the tool, but all my main seals leak when I really beat on
the engine... so there's probably something to it.

Ah - I know about this one. I highly recommend that you follow the
prescribed process. If you don't, you can get a little bit of timing
variance between the timing gear moving up/down (changing the cam timing).
This is because the variance of the dizzy gear to housing clearance and
the end-float in the dizzy itself can "add up" and cause some issues.
For a street motor it almost does not matter, but for a higher end motor
(read high compression and tweaked timing), this could put you in the "red
zone" and you could def. get detonation.
You can see this pretty easily by watching your idle timing jumping
around... If it jumps around at idle, you can bet for sure that it'll
bounce around at high RPMs.
It's def. worth doing.
