Max horsepower with EQ heads?

Part of the reason I posted this is I have raced big blocks with poor heads for many (42) years, and curiosity got to me about these heads.
There wern't any really good head options in the 70s for racing a 440.
It also occured to me that someone like me (retired) that really hurts thier race motor might need to look at a cheap alternative in order to keep on racing.
