Hello, I have a set of 65 hipo heads (double 289 dot, screw in studs, raised spring seats). I also have the intake manifold that came with.
Here is the question. The manifold still has the ID tag, but someone told me that this was not a HIPO tag.
The tag says
289 65 7
5-c 552-j
It's hard for me to believe that a 4 barrel intake, numbers matching, would not have been mated with the heads from the factory. The previous owner stated that he bought the car new
