consensus on aftermarket LT4 lids?

I know for a while there was a good uptick in aftermarket vendors coming out with lids besides Nitrous Express. Have any actually been *independently* tested to see if they make the gains they claim?



I was looking to port my stock blower come fall and was debating on going with an aftermarket lid or not. I also wonder why the lids aren't taller, of if that would run into a hood clearance issue or just wouldn't do anything.
