Not sure what to do

[70CHEVYBB]

I have changed jets from 72 to 67 way to lean and running hot went to 68's the same and had to settle for 70's not a big difference but did help with mileage. I am at 34 degrees total timing. I have a 15 mile drive one way 10 of them are 60 mph the rest is in town but only two lights. I have thought of a cam swap but I really think I might put an edelbrock 650 on it. I really do not like the holley for everyday driving anyway.
