Improve flow of air and fuel through the head.
On an engine with two inlet valves per cylinder it means that there are two ports in the cylinder head and inlet manifold for each cylinder. (IE one for each valve.) Port refers to the passage that air/fuel enters the cylinder through. Older designs had one port in the manifold & head leading to the two valves.
Port and polish is grinding to improve the flow of the cylinder heads. After grinding and polishing the intake and exhaust ports , a cylinders air flow capacity is checked with a flow bench. Further grinding is done to match all ports to the same flow rate.

The fuel lines connect to a fuel rail that is bolted onto engine. The fuel rail holds the fuel injectors that enter into the intake manifold. The fuel injectors then spray the fuel into the intake manifold by where it meets the cylinder head. On the intake stoke of the cylinder the fuel injector will spray allowing the mist of gas to pass into cylinder via the cylinder head intake port.

the intake on a 2.0 split port has a different bolt pattern.
Esslinger engineering makes an aluminum head that flows better then a fully ported cast iron d port head. The d port heads were the best begot esslinger made theirs. At least that's what my research said.
If you mean "fuel" system, the answer would be the intake manifold.
Usually on the driver side cylinder head. Between the front exhaust port and middle set.
Yes
well if ur a mechanic like me just do some port and polish work givs it twice as much gas bore out the carbs or just buy over sized ones maybe even a custom high spun polish crank shave down the cylinder and the head 4 shorter piston through thers a lot of lil things that will make it roll fast
A 3L cylinder head is generally not compatible with a 5L engine due to differences in engine design, dimensions, and specifications. Cylinder heads are specifically designed to match the engine's displacement, combustion chamber size, and port configuration. Attempting to fit a 3L head onto a 5L engine could lead to poor performance, improper sealing, and mechanical failure. It is essential to use the correct cylinder head designed for the specific engine displacement.
