You can also use the heads off of a mid 80's 3.0L Buick Century. The pedestal height is a .100 shorter though. Don't ask me how I found that one out....lol

The pedestals weren't .100 shorter on that version of 8445's but the pushrods were. If that was the case than GM wouldn't list the same replacement head for both that 3.0 and any 3.8.
