Block is cast around sleeves,the original has grooves around O.D, that the aluminum cast into,when bored for sleeve the grooves will be gone and sleeve will be smooth on O.D. also.
Darton,LA or Melling should/will have flanged sleeves.
Sleeve needs to be flanged at top for aluminum block.
BTW if block has hole/crack into water jacket,that has to be repaired and then sleeve installed, the sleeve won't repair the block like it does on cast iron block.
