That has to be most dangerous and ummmm.. 'not best' advice I have ever seen here and I have seen a lot.
Unless you have a machine shop with a milling machine don't be trying to sand, grind, or otherwise screw with the most important part of motors combustion chamber is my advice.
Want more compression and a REAL power increase for $8? Just drop in an NGK Iridium spark plug.
