[Mr.Pontiac]

My car really runs well enough for me personally. Cliff really helped me alot, i never blocked the hole and relocated them further down  inside top section of my rochester.Always looking for a little more top end, is there any real seat of the pants differance in relocated them down further. My exit hole are even with secondary blades plus i knotched the holes and cut a small u in front of blades.17056240 carb. Thanks for all your help Cliff!

No need to relocate them, they are only to supply fuel to get the engine thru transition when the secondaries first come in anyhow.....Cliff
