BMF heads is a CFE company. They are an inexpensive 18* casting with generic port designs. They are meant for someone looking for a good cylinder head without the detail of a Comp or Pro Stock quality head. How much are you looking to spend? There are several good head companies, but you have to decide what level you need for your project. Their 15* was tempting, but I chose to try an SB2 reworked cup takeoff to save money. I am not using a Turbo, not sure what casting/chamber design would be the best for that. Maybe Curtis can shed some light. I'd be interested to know what casting style/combustion chamber works best with Turbo's? NOS? Blowers? Single 4? Two 4? There is a lot of choices for heads these days for the SB. Symetrical port BD Brodix, Canted valve Brodix, -12 Brodix, CFE SBX, Little Chiefs, 15* wedge...... Curtis are your ears burning?
