I posted these on our website this morning, FYI. We're slowly going through parts and purging stuff that we never see ourselves using.
These heads were intended for a full NOS 427 engine, we have an original cam, block, intake. The intent was to build a factory correct engine and see what numbers it produced. The project sat in the machine shop for wayyyy too long and the idea died.
