How does a vortec engine work?

The word 'vortec' is the name of the cylinder heads used in Vortec Model engines in the year 96'+ The engines that use the Vortec cylinder heads are the 4.3L Vortec, 5.0L Vortec, 5.7L Vortec, and 8.1L Vortec. They were only put on Gen I small blocks. If they are any other size Chevy engines and still retain the Vortec name then it's purely a marketing name, the same goes is it is later than a Gen I engine. For example the new 4.2L I6 from GM retains the name Vortec, but it does not actually use Vortec heads as these heads were only made for OHV engines, and the I6 is an OHC engine. The Vortec heads are based on the LT1 and LT4 head after they were discontinued along with their reverse flow cooling design. It is simply an effect made in the head similar to a vortex to better atomize the fuel and air intake charge when entering the combustion chamber, it is not a different type of motor.
