On Harley twin cam heads we weld in a "hump" to aid in the equalization of the air/fuel mixture into the combustion chamber.....it also helps in the atomization process since the injectors are located in the intake.....not the case here though. We need to equalize the pressure in the intake so as to not have a leaning effect as the air moves towards the rear cylinders.
Question for those.....why is the carb located in the center of the intake manifold on gas powered vehicles....and for high performance application both intake and exhaust manifolds have equal runners
It just amazes me that on these 6.0l motors equalization does not apply anywhere...the path of least resistance applies and that does not make an efficient power plant.
