I am going to buy a set of aftermarket heads, adn I am not sure what is the best for my application. I was told to go with a set of cast iron heads because of my supercharger and the heat issue. The cast iron will expand the same rate as the block, which will prlong my head gaskets. I know this is true, but is that my best bet? What are your thoughts? swapping out the pistons to clear bigger valves is an option, just not something I want to do if I don't have to
