i know of a way to push iron golems that spawn inside of blocks the best way ive found is to use observers, pistons, string and piece of redstone on a block, put the piston on the 2nd block of the spawning floor, observer facing in on top of that and put string infront of the observer youll need a block behind the piston with a redstone dust on it to make it work, its an expensive modification but does increase efficiency
