I have a question about aluminum heads, for arguments sake lets say the 440 source ones.
I picked these heads because they are a copy of the stock heads, so the ports and combustion chamber are closer to stock heads vs edelbrock, or Trick Flow ones
If someone installed these heads on a basically stock 68-70 B/RB engine, running the Magnum/Roadrunner cam, would any real noticeable power be gained?
Or will most of the performance potential of aftermarket aluminum heads come from the better flowing port design, and or combustion chamber design?
I have always gone by the rule that the aluminum heads disperse heat so much faster then cast iron, that when building an engine, if using aluminum heads you can go a full CR point higher then you would with cast iron.
If this is true, would a stock 68-70 B/RB engine, "act" like it lost a point of compression installing the aluminum heads in place of cast iron, again if not changing camshaft?
