Is that a cast Eagle crank? Small Block strokers quickly out flow most Stock cast style small block heads. If it were mine, I would put a high flow aluminum cylinder head on it. Trick Flow comes to mind. You can go the “w” head route, which definitely flow really well, but they need matching “w” intake and exhaust pieces IIRC. The point being a high flow head gives you room to grow, which usually happens. This stuff is addictive!
