I finished tearing my engine down yesterday.  This engine was rebuilt by 
Bruce Turrentine over a decade ago.  It wasn't zeroed timed, just tore 
down, checked and put back together with new seals (several of the 
3-piece apex seals are still 2-pieces).  No rust ANYWHERE, even though 
I've not done anything other than keep it inside, and cover the ports 
with duct tape.

The next steps are to:
- mic everything to verify tolerances, but everything has been excellent 
so far.  For instance, I tried Lynn's "apex seal play in the apex 
groove" trick.  Every slot has just under 1/16" of play.

- do an aggressive street port.  I have some trash plates from another 
engine to play with.

- ceramic coat the rotors and bearing surfaces.  I was going to pay to 
have this done...even got a reference from Bruce.  But while 
investigating it, I ran across a comment that stopped me cold.  "Every 
time I've paid to have something done and shipped a part off, my part 
got trashed."  That has been my experience, so I decided I'm going to do 
it myself.  It's more in keeping with what has become the theme of this 
project anyway.  That theme being "I did that".  Ordered the Tech Line 
Coatings chemicals from Caswell last night.

The incredible thing about rebuilding this engine is that every part can 
be laid out on a 3'x6' worktable so that each is visible, and there is 
still workspace available.
