 The heads and intake are Cleveland pieces.  The heads are made by CHI and they are bar none the best Cleveland heads out there.  
The Ford Cleveland head was available in either a 2V or 4V head.  The 2V head was higher velocity, lower flow.  The 4V head was higher flow, lower velocity, so it needed a big inch motor to pull on it, or a smaller engine needed to pull a lot of rpms.  
CHI's head is a hybrid....high velocity, high flow head.  These are only 260cc and use the same intake gasket as the 225cc version of the head.
