Hey guys I was reading your posts. Try contacting C & C Motorsports(
www.candcmotorsorts.com) & ask for Carrol Carter. He produces the old syle Ford Motorsports Hemi Head ( A441). He also has everything for complete engines. He also has blower manifolds for 10.3" blocks. I have ordered a set of hemi heads & a cast single 4 barrel manifold from him. I met him at his shop & he is extremely nice guy & very intelligent when it comes to engines.
