    I've seen many of posts of people saying it's possible and they've done this. But I'm seeing conflicting answers on what exact head gasket I need. Some people say match the head and others said match the block.
  2. Engine
    I was pulling parts off the 454 today and the whole time I thought it was a Gen 6 block. I pulled it from a 99 chevy 3500 suburban. I was looking at the #'s on the block, and in the back side in front of the flywheel it says MK H-5... So im thinking it a GEN 5 block??
