4160 750 holley metering plate spacer? Missing it

[cawcislo]

Hello I was replacing some gaskets on my 4160 holley 750 carb 3310-6 model and when I watched a video on you tube of a 3310-2 version it had an extra gasket and metering plate spacer? Not sure if I’m missing it or my version of carb doesn’t have one? See pic off you tube showing the metering plate, a paper gasket, the metal spacer part and then the blue gasket. My carb never had the paper gasket and metal spacer part.

should I be looking for this part and what exactly is it called?

Some had them some didn't. Yours likely didn't have it.

It was a stiffener plate and gasket. When they quit using the softer cork gaskets that dried up and shrank they got away from it . Dash 4 and later pretty much

To close this thread out I did a bit more looking and my 3310-6 model carb has a flat area under the secondary metering plate so that extra spacer is not needed as the replies stated See pic.

The 3310-2 in my first post has a power valve cavity on the secondary side which looks like this and in this case you need that extra sealing plate for your version Holley. it is sold as Holley part number 108-122
