Kz400/440 head swap

Hey guys winter is fast approaching here in upstate NY. Hopefully Goin to be doing a lot to the Kz400 Ltd this winter. My question is...is there a 440 cylinder set that will bolt onto my 79 Kz400 ltd? I also have a 78 b1 engine as well.just curious a's I know there arent any big bore kits for these bike so I might as well make my own right? Haha. Thanks in advanced for the help and info fellas

It will bolt up IF the sleeves will fit the holes in the uppercase.
