Trick Flow are the best for the price. SCJ heads are good too, but there is a valve spring issue with solids. I perfer the valve spring on the trick flow. This is out of the box, with no mods. A hyd roller is good to use with either head. Yes you can make 700 hp and still be very street-a-ble on pump gas. 9.5 to1.
BBF let them breathe and they can make phenomenal hp.
