These are in excellent condition and come with the the seal ring gaskets.
As shown, one is made by Russell (641090) and sells at Summit for $66 plus another 12 for shipping and 5.5 tax. I am selling for $30 and you pay no shipping and no tax.
The other is from Edelbrock for Holley/others and Summit lists it for $131 plus the 12 for shipping and another 10.80 for tax. I am selling for $60 and you pay no shipping and no tax.
Made for Holley and will flex or adjust for Quick Fuel carburetors as the spacing is different between the two carbs.
