I am looking for the best priced, quality and fitment for my original quadrajet carb base gasket to mount to my edelbrock performer intake. Its a 72 350 with 4bbl. I am taking off the junk edelbrock 4bbl carb. Also is there anything special I need to get to have the car and intake meet up? haven't taken the carb off the intake yet.

I like a 4 hole carb gasket. You should only need to take the old carb off, remove the studs, and install the new cab and gasket.

X2 on the 4 holer. Consider an insulating gasket vs a stock gasket.

Is this a good one?

Yes, but you can one like that at your local parts store.

I used a 1/4" 4 hole insulating gasket on a similar set-up, but always wondered if that was right with the Performer divided plenum. Before starting the swap, do you have the fuel line, throttle cable bracket, bolts, etc. (stock or generic) that go with the Qjet?

JpMotorsports

Yes I have it all for the swap

I use a thick gasket with stiff inserts around the bolt holes. These usually come in the carb kits and most auto parts stores also sell them individually.

This is a Fel Pro 60335, available from O'reilly's Auto for $2.99:

Sorry to threadjack, but I am doing the same thing right now and my performer intake has studs in it I can get out with vice grips. Does anybody know what threads are on those studs? Due to my location I can't just go to the store and try a random bunch of different SAE nuts to double nut it off. I have to order them and wait weeks for them to arrive.

The threaded holes in the manifold are 5/16-18. For a standard gasket, you'll need 2ea 5/16-18x4 1/2 and 2 ea 5/16-18x1 /14 bolt for a Quadrajet.

I guess I didn't phrase it correctly, and it may be a stupid question now that I think about it because it could be anything, but I meant the thread at the top of the studs. Trying to double nut them to back the studs out of the intake they are stuck in. I am ordering ARP studs for the Quadrajet now though thanks to your specs, thanks

The top of the studs are 5/16-24. Since there are 4 studs and for nuts currently, why can't you just use the hardware that you have now to remove them?

No nuts, just the studs. This is a new to me used manifold I am installing that had the studs for an Edelbrock carb in it when I got it. I'm trying to pull those out so I can bolt my Rodchester up to it. Thanks for the help!
