Magnum pistons on LA rods?

Just about the press my MP stroker pistons pins into my LA rods and I find that the friggin little end is too fat for the pistons! Are the magnum rods little end thinner? They must be 'cause these aint fitting into the pistons! SO, my question is: what is the side clearance on the rod to piston suppose to be (dont want too little side clearance or they might bind when I put them onto the crank journals). I had these piston/pins and rods balanced to 1/2 gram of each other now I have to grind on 'em again :devil: ...This is just too dumb.....:gripe:
