Flat Plane Vs Cross Plane V8 engines. A flat plane V8 (animated on the left) is very much like two inline-4 engines mated together in a V configuration. Therefore end-to-end balance is inherent, as the first and last piston of a bank is always exactly in the same position, as are the center two pistons on each bank.
A Flathead is an engine in which the valve is in the block, not in the head, in what is called an 'L' configuration or layout. It is one of the earliest valve configurations for the internal combustion engine and was favored at the inception of such devices for its simplicity and lower manufacturing cost.
