Aluminum Heads for Mild 327?

Assuming you are going to use forged pistons I have done some calculations using ICON Forged Pistons from Keith Black. They are the newest thing out, my machinist recommended them to me when I did my 454 build last year. First set of calculations are 327 block bored .030 and decked to 9.005, 5.7 rods, IC792 FT pistons, Fel Pro 1010 head gaskets, Lunati 10030 HYD Roller Camshaft, Edelbrock Performer RPM heads and intake, and a 750 cfm carburetor. The static compression would be 9.796 and the Dynamic Effective Compression Ratio would be 8.465. This setup would produce approx. 390 hp and 412 lbs. of torque. The second set are 327 block bored .030 and decked to 9.005. 5.7 rods, IC793 domed pistons, Fel Pro 1010 head gaskets, Lunati 10030 cam, Edelbrock Performer RPM Heads and intake, and a 750 cfm carburetor. S/C 11.072 and DCR is 9.588 which I think is too high for the street. Flattops are the winner.
