angle of the exhaust is to produce more power like the Toyota supra almost all the exhaust are angled out so they get better flow which means more power the inlet is for different types of pipes like 2 inch inlet for a civic and 3 inch inlet recommended for turbo performance cars. inlets are to fit multiple different types of cars
An inlet and exhaust valves are two separate things. The inlet valve lets the fuel/ air ,ix into the cylinder. The exhaust valve opens to let the pressure out after the mix has burned, releasing the gasses. Then the process starts over again.
the difference is that the inlet valve takes air (oxygen) from surrounding in order to combution of fuel which result in blast by air fuel mixture and piston rotates while the exhaust gases removed from the exhaust valve.again the inlet valve opens first before blast and exhaust valve opens afterward
The ports of the angle valve ( Inlet and outlet) are oriented at an angle 90 deg.
some of the gases are burnt and reduced befor going to the exhaust

With No1 cylinder at TDC adjust the following valve clearances, No. 1, inlet and exhaust No. 2, inlet No. 3, exhaust No. 4, inlet No. 5, exhaust Then turn the crankshaft 1 full turn so that No 6 cylinder is at TDC and adjust the following valve clearances, No2. , exhaust No. 3, inlet No. 4, exhaust No. 5, inlet No. 6 inlet and exhaust. Both inlet and exhaust clearances ar 0.4 mm with engine cold. This info is from the original service manual
it was invented by a man called Justin Andrews . valva lag- inlet valve closes after B.D.C -exhaust valve closes after T.D.C
Three. Inlet valve, fuel injection valve, exhaust valve.
Hi, inlet is 25mm and exhaust is 22mm
Better heat distribution. The exhaust valve sees a lot more heat.
Inlet .2 Exhaust .4
The intake valve is always bigger than the exhaust valve because there is more volume going in to the cylinder than coming out.
