Hard-Blok is the one drag racers use 'cause its works. For street driving, 
a half-fill is most often used and reportedly only raises water and oil 
temps 10 or so degrees but I haven't needed it so can't verify but a full-fill 
to the top will definitely cause overheating. Problem is, a half-fill 
wouldn't reach up to the areas that cracked on my two examples: they were both only 
  2" down from the deck. So I'm not sure Hard-Blok will do much for many 
blocks. A thin cylinder on the thrust side can be sleeved, but due to the way 
wet-sleeves cut into the main bearing webs down below, most big-power guys 
say to only sleeve one Cleveland cylinder on each bank maximum-   unless you 
BRAZE the sleeves in like Bob Glidden did in the '70s. Then you can expect 
warpage that means remachining the whole block including the mains, cam 
bearing bores and lifter bores. 
Bottom line: if the block has several thin cylinders, its a boat anchor. 
Good luck- J Deryke
