Ported intke question

[hogasm]

Messed around a little with a intake and now have a question about how much material do you believe should be removed around the EGR port.

Do you believe that all the material should be removed including the part where the EGR lower o ring seals?

Also there is what appears to be a baffle next to the intake port which diverts the air away from the EGR valve but also diverts more air to the left side of the motor. What is the real reason for this baffle?

This picture shows the baffle I am talking about

Played with the guts on the mill

Even made the weldable rings and covers. I m not planning on using o rings to seal up the lids but a .125" gasket material that we use that will handle the pressures and temps on these motors. I will make a spare set just for S&G's

I don't have a answer, but I'm interested to see how this turns out for you.
I did notice you have completely removed the EGR cooler portion.

I did remove the external EGR parts, just debating on how much of it to remove internally.

I would remove all of it and weld in a diverter to channel the air evenly between the two branches of the manifold. Nice work.

I had thought of welding a crossover into the rear of the manifold to help equalize the pressures of the two sides.
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.

I got two spare manifolds sitting in the garage.....

Talked to you yesterday,saw the pictures today the work looks very nice.
