Holley carb on my spread bore 440 manifold.

That's a standard square bore manifold, just need to add that spacer to give your carbs linkage some clearance and call it good... beerthirty

Great news, now just need to check clearance for the spacer.

Since nowadays the fuel creates heat related issues you might opt for a spacer that helps insulate the carb killing 2 birds with 1 stone.. just a thought.

Thanks 747mopar. I found a 1/2 spacer at summit Holley 17-59 but is phenolic plastic. Is it plastic to help with the heat? is plastic something I would want to use?

Phenolic is a resin made by combining phenol and a aldehyde, so technically it's not a plastic. Some times classified as "Bakelite" It's often combined with various substrates ( canvas, glass etc.) and is compression molded. Sorry I went a little geeky.
To answer your question, yes it will work on your application and yes it will help your carbs heat percolation issues.

No problem with the geek stuff always willing to learn more. Good to know
