350/255HP Help please

I know what he's going through. I used to have a fairly good running car until I finally just wore my factory block out. I then went and put a Dart little m block in it and 4 years later I still can't make it run no matter what I do. Tried heads, all different kinds of ring packages(total seal luniac etc etc) cams and I've never had it leak less than 10%. Is it possible for a dart block to not be any good. Ive had some pretty impressive machinist hone the block and nothing seems to work. I'm about ready to go back to a factory block. Hope you find out what's wrong.
