Compression ratios

Fixer · Jan 21, 2009

Anybody know how many different compression ratios were available on 113-123 engines. I took the head off my C to machine shop. Found crack beteween exhaust and intake valve on number one cylinder. Head was 1951. Took three other heads to him. All the other heads had shorter valves. We got to checking. They also had bigger chambers. Other heads were also older heads. Now have to look for another head. Thanks for listening to me ramble. Bernie Steffen

caseih.com search for parts will give part numbers. Look for gasoline only heads. the ones you have found are for distillate. Heads from early 123cid engines will also work. JimN
