The traditional solution to this problem with block molds like those is to spray mold release on a piece of glass, overfill the mold and press the plate glass down onto the top of the mold squeezing out the excess for flat-backed castings. try to set the glass down on the resin pool starting at one end and moving gradually to the other to prevent bubbles, takes a bit of practice but results in pretty much perfect backs on your cast parts. Obviously leave the glass in place until the resin sets.
you sound kinda like kermit the frog

lay down a piece of glass on the mold after filling. Makes for a nice, smooth, flat surface when cured.
