Iron vs aluminum heads
Ok I have a set of max ported 6x -4 heads on my turbo 455 motor roughly 9.5 to 1 compression would I see any gains / benefits by going to a max ported aluminum D port head , besides the xtra compression ? Also are the size of aluminum heads exactly the same size as iron heads , because I am very tight with my log manifold to the frame now ..and all my hot air crossover pipes were mocked up with the iron heads . Thanks
