Yes I do believe they are CT heads. However after doing some reading about them, seems some are not great, had issues. If you plan to have the heads done or freshened up, I see no issue. Again these were pulled from a running engine, with no issues or symptoms of this problem. None the less I understand.

 

The problem is with the casting itself. Not really anything you can do besides weld it back together. I'm gonna have to pass. sorry.

 

No worries

T T T..

Even being the CS heads, I would figure if they were going to leak they would have done it by now, again not all of them had the issues.
