IMHO if you are going to...forged pistons and rods... and have to have the crank ground you might as well go to a SCAT stroker with dished pistons for pump gas
you are going to have to balance anyway so factor in all the cost. benefits

now do your research on your heads
do not chase high lift flow cus you will never use it on the street
