Camshaft suggestions

I’ll just say be careful of head and cam envy. I run my 360 with 318 heads and a 256 comp. I’m no expert but my wallet and opinion says it runs awesome up until 5k then it’s done. However, when I turn the key it fires right off without hesitation and purrs like belly rubs on a kitten. Built with the only resources I had at the time. I do have 915’s sitting in the garage, but the engine runs so good right now I’m reluctant to switch them right now. If it’s a cruiser I would run the 318 heads. Save the money for a good set of aluminum heads later on.
