You need to run the "stroker" pistons because of the longer rods(stock is 150mm). The wristpin is moved up higher in the piston to offset the size of the longer rods otherwise they pop out higher than your block. As far as size I dont seem to understand what you mean the size depends on the condition of your block, if its virgin with good walls take it to a machine shop have it clean and deglazed to see if you can run standard size pistons. In the case your block has scratches in the cylinder walls you might need to bore it out, again depending how deep the scratches are. Just remember if is in too bad of shape where you have to bore it out more than 60 over you might want to look for another block hope this helps.
