Dog it all you want. If you had a bad experience, don't fluff it up. .....and I'm not sure if you know this, but to tune with the springs, you choose the spring that's closest to half your vacuum reading at idle. In other words if you have 20hg, choose the 8hg spring, as I think that's the highest one. They make no mention of that anywhere in the deestruckshuns that I've found, but I got it straight from the Holley tech line and it's worked for me. That's the only mod to mine I made. Mine has 6hg at idle so I put the 3hg springs in it and it works well. You can also choose to tune using cruise vacuum. That's how I do it with t Holley style carburetor and it works very well. I've not tried it with this one, yet.
