Hey y’all , I’m building a 74 motor home 440. Nothing crazy, but need some advice. There are so many options for heads and it seems everyone loves the 915 and 906 cast heads. I’ve looked into some entry level aluminum heads and it seems there are a lot of Chinese trash out there but many people speak highly of Elelbrock and Trickflow heads. My question is, are the aluminum heads leaps and bounds above the cast heads of the 60’s as far as potential hp?
