Going to play lotto 440

So a few weeks ago I purchased a 1973 440 block and 727 for 400 dollars. After looking for months, found it at a neighbors house that backs up to my house. He also has high performance heads for 50 dollars. I bought those as well. Ran numbers and they are 64 stage III Max Wedge heads. I want to use these but don’t know what else is needed...please help
