AFAIK the pistons are unique on the 4 valve per cylinder engines.  If you
install a 4 valve head you lower the compression ratio to around 8:1 which
would take away a lot of power.  Personally I would see if the 95.5mm crank
would fit the 3B motor... or see if the 2.0L 16V VW pistons will fit the 3B
motor...
