If it were myself and looking to keep it as inexpensive as possible, I’d just use a set of stock 340/360 heads and call it good. Some good machine work in making the head as good as possible without porting would be all that I’d do. One of the issues here is the cam is very small.
A few problems here;
You didn’t state what the compression is. What octane are you running it on? If 93, will it run on 87?
You said it’s running an Edelbrock intake. That’s great! Which one? I can make about 6 that will bolt on.
What size tire?
What’s the cars weight?
Stock rockers?
A/C car? P/S? P/B?
