Well, the 96 is a hydraulic roller.. your 85 is not..
The nose of the cam is different. I am not 100% sure you can use the later model cam in an early block. I thought I have heard of some guys doing this.. You will also need Aftermarket Roller Lifters which are not cheap and new push rods.
For the work involved unless it is Free I would pass. Not even sure how well it would perform due to the intaske differences
