That is great that they worked for you but I don't recommend them to the average guy because there really isn't much adjustment capability on them. If they aren't correct out of the box it is hard to dial them in. No jets in the idle circuit, air bleeds can't be changed, no secondary jets, etc. If they come out of the box close enough then great, if not then what? A good set of adjustable Holley carbs is super expensive.
