Maybe this is a dumb question but do you get a gasket to fit the carb or the manifold?
I believe a FelPro 9100 would be a better choice because of your intake, not the carb.
The 9100 is an "open" design. If you go this route, order 3 or 4 for future spares.

Please do not use either of those....you should not need any kind of spacer for an Edelbrock carb on a Performer RPM intake......this is what I believe you have.
ESPECIALLY do NOT use that miserable four hole spread bore to square adapter........they should be forced to quit manufacturing those after removing them from at least twenty cars that ran "bad" in my life.......I will not even work on your vehicle if it comes to me with one on it. Yes...they are that bad. A lot of Bubba type characters in my home town in SE Michigan over the years took it upon themselves to bolt Holley's on Q-jet intakes in the 80's and 90's and they should have been shot.......not one of them would listen to me until they spent at least $500 trying to sort the awful part throttle running.
I had to have one on the 66' in my avatar because the 2101 Performer that was on it had a very minute leak across the whole front of the carb......it had an off idle stumble I found to be a vacuum leak and saw carbon witness marks in the front carb area.......this cured it.

Edelbrock states that you hae to use this plate to prevent an intake to carb leak, Phenolitic spacers can be used above this plate. It was stated in the instructions I got with a air gap performer I boought
It appears to be the Performer Air Gap with the dual bolt pattern and the spread bore type pad....I have circled the areas in green that are the problem areas that the 2732 plate will address.....
My own 2101 leaked around the front of the carb base circled.....this was due to an old model 1406 Edelbrock....the newer ones are better in this regard.

Japery,
A gasket is designed to seal two items together without leaking. As you can see in photo / post #68 the gasket has no material under the four hole plenum area.
That is just some fiber hanging in mid air doing nothing. If you take a look at a FelPro 9100 base gasket, post #63 you will see that an open style will suit your needs a little better than the four hole style. Or the gasket underneath that, might be better yet. It copies your intake but not your carb base.
(Had you had some type of four hole style intake, then, you would have had the correct gasket)

wouldn't that cause a lean situation? Rather than the rich plug fouling scenario described ?
Correct. Like a sailing ship. The more air (wind) moving the more the ship "leans" (list).
But anyway, O.P. has a spreadbore intake designed for a QJet or even a Holley will work. I know nothing about those Eddy carbs other than they sit sideways (bowls on the sides) something like a Carter I guess.

Better than what you have now. You can also get this with a aluminum heat shield that fits under this thick gasket. I have used this on the Eddy 2101 Performer intake with a Holley 4150.
Not sure about fitting your Eddy carb. I have never seen the throttle base plate of the Eddy carb. May have to trim the center tab section but it should fit your spreadbore ok. I believe its designed for Holleys. IDK
Summit's site says the 9266 is a direct replacement for the 2732. However it also mentions 4.5 psi max for an eddy carb.
A:If its a performer series carb, yes you need a plate. You should post the carb model number for a more accurate answer. If you experience hard start problems in warm weather after the car is at operating temp, you will want a wood or plastic spacer. Edelbrock carbs have a fuel boil problem. If you have flooding issues when its cold then you will want to bring the fuel supply pressure. Edelbrock states their carbs dont need over 4.5 psi fuel pressure. I installed a holley fuel regulator to solve my problems as well
I just installed the regulator(Holley 12-803) and tried to start but the gauge still reads 7lbs. I tried adjusting and nothing happens. Could it be the reg? It looks very cheap to me. Checked the plugs and they were drenched with fuel. When I turn over the engine the fuel gauge should read the 6/bs ,right, or does the car have to be running?

I prefer 5 lbs.
Be sure the gauge is on the Carb side of the regulator.
