Looking for some thick carburetor gaskets ??

Hey everyone.,

I'm looking for a good and hopefully inexpensive 1/4" thick open Holley carburetor gasket.

I'm running a Edelbrock RPM air gap and want a open 1" spacer. I have a 1/2" nitrous plate but figured I would add 1/4" gaskets to get my 1". I see Mr. Gasket sells 1/4" gaskets but I have had some serious issues with that company's quality in the past.

Thanks
