Those 4 pistons were burnt with a hole on the thrust side of the pistons. I would think the piston slots would need to be all one way not random. I need a Flat head expert to answer this. I have rebuilt lots of Ford engines but never a Mercury with these pistons ,
A picture or two would be nice. By slot, would you be referring to the chip taken out of the piston face that is on the thrust side to clear the head?

Or, try this: http://www.hotrod.com/techarticles/e.../photo_15.html
