you could easily do the cross bar for the aircleaner. i have a common long fuel rail. the regulator goes after the rail so no starving of any of the injectors. the rail was bought with no injector holes and my machinist did the injector holes in it also. i bet he would do both the rail and intake for around 100.00. i don't think there will be any problem with the shared port for fuel dist. if there is i will stage my injectors by using two separate banks. i am using a holley c950 computer. you'll find almost all injectors have the same dimensions.
