318 LA rebuild after losing a valve seat

if you can read the number on the crank someone will know what year and source it is
glad you have both sets of rods
hope you are ok without a balance job
Your are good to go on the torque to yield issue
check your back and forth free play?
get the thrust cap lined up with the block :)
(both thrust faces lined up)
take a light and check
the fix would be easy
