I hope they work for you. The corvette's were straight down in a truck they need to curve back to miss the motor mounts.
Post some pictures when you get them.
This is something I have been waiting on doing. I want a factory set to have cleaned up and coated.

I have got them on my 72 4X4. The miss the motor mount on mine(I assume a 2 wheel drive and a corvette use the mounting holes on the side of the block also). They might hit the cross member on a 2 wheel drive though? I can post pics of mine if anyone wants.

With the v8 in 6 cyl mounts, I had to use the straight down manifolds as well. I have thought about getting some of speedways ram manifolds, look a lot like the one pictured at the top of the link you provided, Speedway even offers them in stainless.

This is pretty interesting also. This is why I went with ram horns.
