Oh, there goes an hour plus, most of it wishing I knew what they were
talking about. I started reading and now I'm hooked. If I can retain
2% of this, I'll double my knowlege :)

A good discussion of the above topics, David Vizard is among the posters
and
the following quote is from one of his posts:
The point about the course grit emery roll is one that novices should
really
pay attention too. a 60 grit emery roll on the intake not only removes
what
ever nasty bumps there may be but also helps offset the rivulet flow of
wet
fuel deposits. Any intake port that has a super shine is designed to
catch the
un-informed novice who stiil believes that 'port and polish' is for
real. The
only place a shine should exist is in the chamber or exhaust and that is
not
to the exclusion of any surface designed to shear running fluids.
Remind me down the road that I have an interesting story about polished
ports
and difficult to convince folk who still think a polish is the bee's
knee's.

It is a long thread at 21 pages, but a very good discussion!
Happy Reading!
