Every pic I see of Hypertech's 160 for the LT1 is this one:

But that image name is 1009, and the part number is 1008. Could be a typo, but there is a 1009, for the 92-94 4.3L
So does anyone here have the Hypertech that can verify if that really is how it looks?
Which leads me to this: How important is that bottom check valve? If it doesn't have that, is it really that important? I figure GM wouldn't have it if it didn't serve a fairly important role...
Sorry to make another thread, but editing the initial post's Subject line, doesn't reflect on the forums :\
