Easy to do on number one. The magnet or claw tool will get it done. Even easier if you pull the distributor because it will let you put some light down there and give you a place to slip in another tool/access hole if you need it to get the lifter out.

Look at the lifter pretty close once you have it out - - it can still have a break-in failure even after the pre-break in service. If it looks perfect externally - toss in a new one butterred up with the appropriate cam sauce and get her going.
