Yes it is the underside that is thicker the skirts are the same on each piston that’s what I didn’t understand because they are R and L pistons for each bank. That made think if the thick area was for heat distribution from exhaust side.One thing I learned on this build is don’t build a shortblock around used pistons. LAL thanks for the replies
