I found a source for my correct date coded 2bbl intake. So, my question is, before I buy, when Ford would build a 289, (in my case) would the Block, Heads, Intake, etc, all have the same casting number date, or are the date codes just within the same time era. I assume they wouldn't match by the exact date, but if I knew for sure I wouldn't have to ask
For example heads and intake manufactured within a month or so of each other?
