The stock CC risers for the CC 427 have a replacement that is made out of copper.
It appears that the copper replacement has one less coolant hose connection port.
I have been told that these copper risers were specifically designed to replace the CC 427 iron risers, to prevent rust out.
Can anyone provide some insight as to why the copper risers have fewer ports?
Are some the connections, such as the cross over line, not required?
