I believe this confirms I need to have the head worked on. Here are my compression readings
Cyl. Dry. Wet
1. 150 150
2. 130. 130
3. 145. 140
4. 70. 70
5. 145. 145
6. 145. 145
#2 fouls a plug , I was surprised that 4 was so low.. It is a 235 in a 1962 C20. It puts out alot of blue smoke. I adjusted the valves.
What does this say to you experts?
