The rest goes through heat and have to be cooled down which gives the next problem in small chassis. And as a top of bad engineering they put on a to small high revving blower which heat up the inlet air more than it should be.
I swear Fords coyote with a 2.9 ltr. whipple would do much better in the Corvette with no overheating and same cooler size.

2 valves per cylinder is only an issue when displacement is limited. If I remember right, LS3 heads flow about as much as Coyote heads, despite having half the valves. The Coyote bore size is very limited, so they have to use smaller valves. The 6.2 liter bore diameter is much larger, so they can run a bigger valve without shrouding issues.
