Exactly right. There is a crossover passage then two lengthwise passages, one per side. The longways get plugged just to the inside of the bolt holes that fasten the hat to the blower.
The injectors are 85lb/hr Holleys. Low impedance (PITA) but 2 for $25 new on ebay.
Controller is a MegaSquirt which is built and tested from the basic kit (CPU and PCB). We will have around $600 invested in the complete EFI system (including the Enderle Bugcatcher) when done.
