Harm? Probably not.  Back when I was in college I had a 65 MGB with a 
knackered engine.  I pulled it apart and found two short skirt pistons and two 
long skirt pistons.  The car ran fine for several years before I tore it down. 
 If you're not going to rave it or drive it hard on the street it will 
probably be fine.

The most bizzar piston mod I heard of was on a Model T that had a a bad 
knock.  Turns out someone hand made a piston of hardwood.  Once it got hot it 
preignited the gas pretty effectively.
