318 cam and intake suggestions

I think the Lunati 268 would be good. It's even "a little" big for a 318 but he said he wants sound. That cam would sound good and run way better than the 508 or Whiplash. Cheaper too.
With that lunati cam he is gonna have to spend a lot of money to make it work with stock heads. I have a size smaller and had to cut the valve guides , new valve seals, and get new springs and retainers It will give him the sound but it's not exactly budget.
