Jerry,
Thank you for your response. We saved the 1 and only shim that was on one side of one cap only. We believe someone was in the motor recently. You are correct. The cylinder tapers wider towards the top.
The great news is I Just found out minutes ago that my Friend and auto therapist located a 1955 235 to swap in And has someone interested in the 216 as is so a win win and great end to the day, I appreciate your response nonetheless. As I am new to this forum I would like to either remove the thread or make everyone aware that this is now a moot issue for me as I do not want to waste anybody’s time. Any suggestions.
Thank you again!
Patrick
