Another Holley jet question.

I'm making progress on my 67 Barracuda and it's time to rebuild the carb. I have a Holley 4165 650 cfm. I'm putting it on a 74 360. The engine is a mild build 30 over 9:1 compression stock heads mild cam what we used to call an RV cam, I don't recall the specs. And headers. I will be running a 4 speed. I live at 4700 feet elevation. Just street use no racing. As I'm tearing apart the carb and I noticed it has size 58 jets, that seems a little small to me, I was thinking 64. The power valve is a 7.5 that is in the kit if that makes a difference. Any suggestion on jet size?
Thank you.
No one can really help with recommending a size because every situation is different. Run the carb as is and tune it for what the engine needs!
