65 Barracuda 318 Rebuild, Cam, timing, lifters maybe a kit?

I'm betting that the OOTB Eddy's will outflow the max effort "302's" just because the smogger 318 heads start out small valved and with the tiny port window.
I was just wondering like on a budget or a car you dont want aluminum heads on if the 302s could match. What are size valves are in a factory eddy?
I personally don't like the look of aluminum heads I guess I'm weird but I'm also not a racer I like an authentic and original appearance engine in a classic car.
