I'm the original owner of a '69 Barracuda 340 that I ordered in the fall of '68. Recently I removed the manifolds for the first time and took photos. Factory was 2 thick conical washers at the front and 2 at the rear with no washers in the middle 2 places. So yes, four washers on each side and no washers on the inner two bolt locations.
These photos are left side: front, middle, middle, and rear. Right side is the same as far as conical washers.
And AMK is the best source. AMK has actual size color photos of each item they sell, so you know exactly what they offer. Items that are exact copies of Mopar fasteners are coded with the pentastar logo and show the Mopar part number. Others who sell fastener kits are mostly just re-selling AMK.

The AMK kits are retailed through some vendors and then there are similar kits that put together from a variety of parts that I feel are not of the quality of the OEM parts. So just try to determine what your purchasing to avoid any frustrations.

I don't recall the factory using gaskets. Doesn't mean they didn't though. My guess, the heavy solid center section stays put, but the long thinner arms to the outside would be more prone to expansion and movement.
I have mechanical Aptitude. I can screw up anything.

340 exhaust manifold gaskets from the factory: driver side had the heat shield/gasket. Passenger side - no gasket.
Concerning the thick conical washers on 340, there were 4 on the driver side but only 2 on the passenger side. Photos above are the left side showing 4. Photos below are the right side showing only 2, front, middle, rear.

They are recessed quite a bit. Special long bolts.

Hundreds of times I have soaked fasteners in vinegar for usually 2 - 3 days, and I usually hand wire brush each day to physically remove rust residue in order to speed up the chemical reaction. Works every time, and the fasteners are then ready for phosphating (Parkerizing) or zinc plating.
These exhaust manifold bolts have minor cosmetic pitting, but are serviceable.
