David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting

I have a question. I bought a 318 complete motor from a friend who needed money. It came out of a '69 Charger. I haven't done anything to it, or even looked at it, sits in the back of the shop on an engine stand along with 4 other motors from different automakers. Where would I find any information about the motor, the heads, etc.? Thanks in advance. By the way I enjoy reading the back and forth between two people who under different circumstances could have been great car buddies with each other.
