I dont think That hole is supposed to be there.
I was putting in new valvesprings and I took out the spark plug for this cylinder and turned the motor, and antifreeze shot out. I pulled the head and this is what I found, the rest of the cylinders look good.

it'll be cheaper to junk it and start over. that hole, you automatically need a sleeve and a piston. if you're going to sleeve it and put a new piston in, you might as well bore the other 7, and put new pistons in them as well. and as you may or may not know, you cannot compress a liquid. so, that rod is probably shot, and your crankshaft may not be doing so hot either. just buy a good used one, or a core and either have it built, or rebuild it. i'm assuming since you pulled the head, you have the know how to rebuild the shortblock.
 
Yea the rod is gone, because after I found this I rotated the motor and the piston didnt move, I had to tap it down to find this hole. I am not sure what I am going to do. My dad has a 454 and a couple 350's so I will probabally build one of them
