Default Cossy, which pistons?

My brother is rebuilding his cossy engine gonna be running around 350-400 bhp.
At the moment the bottom end is standard.
It will be running a t34 hybrid if that makes any difference?!
Which size and make of piston should be used?
Cheers john

mahle as standard, very good mate
size will depend on his block bore size , try and get the 4x4 ones with the valve cut outs . Seems to be the better choice , think 2wd ones suffer more with piston slap not sure on that though.

He would like to keep the bore size as close to standard as possible, any one know what a 205 standard bore is?
