So I throwing around the idea of building a 5.2 magnum for my 65 valiant. I have a 273 from a 1967 barracuda I'd like to use but like the idea of a roller cam. I have a 4V intake from a 70 340 I'll be using. Question is should I drill my mag heads for the LA intake or buy a set of Chinese EQ heads that have the holes already drilled? How do the new EQ heads compare to stock mag heads? Would they be worth the extra money? What roller cam would be comparable to the Hipo 273 flat tap cam? I'm just in the planning stage currently so any and all opinions will be taken into consideration! Thanks fellas!!
