The above numbers of 10-1 with iron heads and 10.5-1 with aluminum are a good safe number to go by. What are your intentions with the car? A point of compression may not gain enough power to warrent the potential tuning problem or the need for better fuel. Will this engine be N/A or planning on a power adder? I think knowing the goals of the car will help lead you in the direction you need to go.
