  • Swapping Cylinder heads?

    I need to swap the head on my mini with another motor I have. I have never done this before. What should I do before putting the head on?

    I took the donor motors head off. Here is a picture. Anything I need to do to it before putting it on?

      If it were my cylinder head, I would take it to an auto machinist and have him check it out.
      Clean it.
      Crack test it.
      Have the head face checked for any warping and skimmed, if necessary.
      Check valves. You'll likely need 4 new exhaust valves, at least.
      Check valve guides. You'll likely need 4 for the exhaust valves, at least.
      Purchase new valve stem seals.
      Have the exhaust seats replaced with hardened ones, if not already done.
      Have the valves seats ground.
      Have at least one chamber cc'd so you can make sure the compression isn't way too high.

      I'd also clean up all the threads on the exposed studs and blow some paint on the newly cleaned head.
      The more I know about Minis, the more I know I don't know about Minis.
