Will a Penta B234 86mm stroke crank and rods fit into a B20 engine. I realise I will need to modify the front of the crank to fit the pulley. Any assistance appreciated

No it will not fit

Bearing size is smaller and teh front of teh crank is the wrong shape

You can get stroker cranks for B18/20 engines
