intake gasket questions

Garrett Ellison said
Why are you using an action plus? The iron 340 manifold is better than it is, as the Weiand has 318 sized ports that extend deep into the manifold. If at all possible, switch to a performer RPM, an LD 340, or an iron intake. If you do continue to use a 318 size port manifold, a Fel-Pro 1243 gasket (273-318) may be a better option. Also check manifold fitment with the following.

Honestly, I've had this car for about 30 years and that's the way it came. I don't have another intake but I'm not opposed to swapping. Here are the specs the way it sits.

71 Dart Swinger with 73 340 engine, small valve J heads, and Mopar purple shaft 284.484, 340 cast iron manifolds, Holley 3310 vacuum secondary, Weind 8007 spread bore intake, 727 and a 8 3/4 3.23 rear. Ran 14 flat and was a decent cruiser in this configuration but I don't care much about racing anymore and just want a reliable cruiser that looks, sounds, and starts like a stock car.

I had the super quad laying around and thought it would be a good match for the spreadbore Weiand intake. Kinda tired of fooling with the Holley and it needs a full rebuild at this point.

Any advice would be appreciated.
