yz 426

i just got a yz426 to put in a yfz450 quad that i have been peicing it together from scratch off ebay and i was just wondering what crank, pist and cam parts will interchange. the motor itself bolted right in. but im looking at doing a bigbore and porting but i mainly want to do a stroker so i need to know who i can send my crank to so i can get it stroked or if i can use a 450 wr crank if i use the parts to go with it. thanks for any help.
