This is why I didn't undo the timing belt when I did my lifters.  It's
almost like doing the whole tb/wp job just for that.  I figured, if the
cam seal ended up leaking, I could just do what i skipped the first
time, but it all went together properly.  This was
discussed/debated/argued at length a year or so ago on the list, with
Scot Justusson recommending the "leave the camshaft in and tilt it
forward" approach.  I tried it, it worked.

So, anyway, what probably happened to you is the the tb was loose enough
  on the crank pulley that it did not go back where it started, or at
least, the two pulleys ended up "off" relative to each other.

You really need to find that crank mark.  A slow turning of the engine
(big ratchet, coil unplugged), while cleaning and looking carefully,
will turn it up.  Obviously it will also be when the #1 cyl is at the
top, so you don't have the search the entire 360 degrees, just a 10-20
degree window or so.  Find it, clean it, mark it with a paint pen, and
make sur ethe crnak and cam (and dist) are set right.

Then do as Javad suggested and check your ignition timing.
