What are you talking about?
As long as the car is tuned it will have good gas mileage. Doesnt matter how much power it has, if its on pump gas, cruising down the highway, how is hurting the fuel economy?
I just delivered a car to a guy that has me install a roll cage and fix some other stuff on his car, the car ran 11.8 on 19psi and pump. I had to drive it 300 miles to deliver. The car used 10.4 gallons of gas. Tell me that car does not get good fuel economy because it has power.
As far as the head decision goes... I personally like the 2g head. The bowl, valve angles like you said, smaller ports and so forth. I gasket matched my intake ports to a 1g intake manifold which possibly hurt it but I am going for the most flow I can get. I dont think anyone as ever done the test, stock head for stock head to see the power difference. Would be interesting to see in my opinion.
