Question #1: Was the FORD 255 DOHC V8 Indy engine a flat crank? No.
Question #2: Didn't someone many years ago offer headers for the "FE" where tubes ran under the engine to change sides to tune the pulses?
Yes, several Header companies made "Pan Warmer" headers that crossed some of the Header Tubes from one side to the other side of the engine. The idea was to even out the pulses in the exhaust and possibly improve scavenging of the next cylinder firing in that collector.

ps It did have a three oil pump Dry Sump system 1 Pressure and 2 scavenge pumps
