tapered carb spacers

Ok folks, lets hear the good, the bad, an the ugly as it relates to the use of the tapered carb spacers like the HVH Super Sucker and the Wilson Manifolds spacers.

I'm considering testing one against my current (likely not optimal for the combination) 1" open spacer on a Vic jr intake, 454 bbc in a 3580 lb car.

Would like to hear any and all feedback on the usage of these spacers.

From other posts in the past, I've read that the results vary greatly from no change to as much as .15 in ET.

Also, if possible, mention what height spacer was used and what it was compared against.

Thanks for any input
