Mike,
For not being familiar with how to post, I'd say you did a pretty good job.
It's interesting that you chose to go to such great lengths to learn the
proper way to do an engine.
Hang in there and buy lots of LBCs (little or lovely or lousy or
licentious or lovable British Cars) so you can put all of you knowledge
to work.
You'll find lots of interesting info on this line and I'm sure you'll be
able to impart a goodly portion as well.
Best Regards,
Tony R.
