Timmy,
I will suggest to forget that head. It is a low performance head for early 396.
Instead look for either the Last casting number digit of 049 or 781 in an oval port open chamber head. You can at times find those at a good deal and with little work and some compression can make a lot of power with them. They were used in some of the 1971 to 1974 Truck and passanger car engines. Even with a mild street engine you can easily get 500 hp with hose. In race trim with bigger valves and minor porting with good cam and higher compression in a 454 style engine you can go over 600 hp with those little heads.
