Nathan,

If it were mine, since he will be removing the valves anyway, I'd go all the way and have the block stripped of bolt-on parts and properly cleaned (with something not harmful to babbitt bearings.)

Add a distributor to your wanted list. That's an A and inferior to the B with its centrifugal spark advance rather than the A's manual advance. The fuel pump is installed upside down so I cannot see enough of it to say if it is for sure an original, but from what I can see, it looks to be one. Likely it should be rebuilt, which is an easy DIY project.
