I have got a 68 ss 396 325hp with edelbrock torker single plane manifold with a holly 850cfm carb, trw pistons. the block is borred 60 overbore and has a crane cam i think its something around 500 lift 300 duration i also have a set of hooker headers on it . I am looking to get a set of heads for the engine but im not sure what to chose I want cast iron rectangular ports not aluminum because im on a budget and im not sure what size intake portsare the right size for this engine any suggestions would gladley be appriciated. thanks

The car is a street/strip car so it will see time on the track but more often on the street but i do want to make maximum horse power so i think i should stick with a set of rectangular port heads. These are the heads i have narrowed it down to:
1: BB-Chevy Dart Iron Eagle Cylinder Head
ยท 308cc Intake Ports
ยท 119cc Combustion Chambers
ยท 2.25' Int/1.88' Exh Valves
ยท 1.550' Springs
2: BB-Chevy World Merlin III Cast Iron Cylinder Head
ยท 320cc Rectangular Intake Ports
ยท 119cc Combustion Chambers
ยท 2.300' Int/1.880' Exh Valves
ยท 1.550' Valve Springs
3: BB-Chevy Edelbrock Performer RPM Aluminum Cylinder Head
ยท 315cc Rectangular Intake Ports
ยท 118cc Combustion Chambers
ยท 2.190' Int/1.880' Exh Valves
ยท 1.550' Valve Springs
I think that the 320cc world merlin heads may be a little to big for my application what do you think I should chose???
