I've played with the numbers in the spreadsheet, and I can't get much 
difference even when the stock length is less. For example, a stock SBC 
is 5.7, long rods are about 6.2. The arguments about weight and friction 
are more believable.

I already had this spreadsheet laying around.  Long ago valve timing was 
given as piston positions rather than angles. It makes more sense when 
you think about it.
