as listed above I was told the same from a respected SS cylinder head builder "heads are under development to be released soon."

In addition, he told me Edelbrock has taken feedback from several front line cylinder head builders asking, "what would you like to see revised with this casting?"

To me, I expect at some point in the future replacement heads will be the norm.

If I was just now beginning my Super 10 engine & chassis project I would most likely wait for the new heads. Now that I am 9 months into the project and have a conventional iron head package almost finished I am going with the original plan.

I will be watching the replacement head development with interest for possible future upgrade.
