Yea, since the intake sits on top of the exhaust manifold on this motor, if I remove the stock ex manifold there will be a hole in the bottom of the intake manifold that will need to be covered. I have noticed that some people recommend plumbing the exhaust gases back to this cover using some tubing and fittings attached to an aluminum plate. I also have noticed that some manufacturers use a water system to warm/cool the intake...
I am not sure if I close off the bottom of the intake to install a header if the truck will run as well. I know that this aids in warming the motor on cool days but am not certain if there may be some other reason.
