<VV> 1963 versus 1964 Exhaust crossover

The "extra room" came from modifications to the crankcase and the rod 
length - with changes to the wrist pin location on the pistons.  I suspect 
that the mod to the crossover (I'm not an EM guy) may have had something to 
do with the addition of the transverse spring.

Later, JR
