There is further discussion on WFM, but here is an update.
I found the intake valve stuck and a rust ring pitting the cylinder about 1/2 way up the bore.
There are 3 head studs needing replacement. Small job has offered me some for less then the $23 each they are from the usual sources. I'm not sure I want to invest time or money in this block. I'm not doing a rebuild, I have my doubts the .030 over would clean it up, I haven't found a marking on the piston to see if it's std.
I also have two other possible solutions that are available.
First, swap the engine for another from the same seller.
Second, cannibalize a 71 110 I have that runs but isn't selling for $250. I don't know if the short block is compatible if I saw everything except the block and internals like the crank.
Thoughts?
