Spacer plate engines are supposed to have more low end "grunt",you will get mixed reviews on this.
250R brakes will not work on the EX spindles without some high priced adapters,the EX spindles will work on the R otherwise.
Barnett,EBC,etc all offer heavier springs,and CR500 springs will do the trick also.
 
The 86 piston on a long rod crank doesent really do anything to the port timing,everything is moved 5mm so in theory it is still in the same spot as far as piston to port opening.It allows for more crankcase volume and as mentioned before,a wider range of bore sizes were available in the 86 style.
