Anybody have any recommendations on a set of intake manifold gaskets for my 340? I don’t do this enough to know what works better than what…

What intake, iron or aluminium?
Ported or stock?
2 or 4 or 6 or 8 barrel, high rise, mid or low. Dont know that it matters but it does make the conversation a bit spicer!

Regardless of brand, many people leave out the front & rear end gaskets and just use silicone. Some end gaskets squeeze out and others are too thick or hard and don't let the intake sit low enough. Make sure the intake lines up properly with the side gaskets in place. Depending on any other machining, you may need to mill the intake a bit. You don't want to elongate the manifold bolt holes.
Iron stock heads … .. . Duel plane aluminum with a 4 barrel.

This is what I used on my Edelbrock Airgap with no issues. No china wall gaskets. Get a good phenolic spacer for under the carb, Edelbrock has these also. Check out the Holley web site for parts.

I just bought a set of victor reinz 360 style ones (not the stamped tin 318-2bbl style ones) yesterday. Rock auto has them in their "clearance" section I think they're like $8.something a set.
Used to use alot more victor than fel pro mostly because that's what my old go to parts store carried. Look up some 70s Mopar, I happened to be looking up stuff for my 78 fury 318 and they came up there.
Look at "clearance only" section, and look thru the clearance/wholesale section, you'll find em

SCE and Superformance both make good gaskets. I agree with what others said about no gaskets on the china walls.
I just finished test fitting my Mr Gasket #5840 intake gaskets and found the same issues as mentioned above. The China wall cork gaskets measured about .19” thick and would not allow the intake to sit low enough for the sides of the intake to sit on the head mounting surfaces. I too have filled the China walls with sealant after removing these gaskets in the past, but this time I wanted to fill these areas up a bit since I had some time before the install.
So, I remembered reading a thread on here about another member buying a gasket kit with sheets of different thickness/materials of gaskets. The kit that I found was the Fel-Pro #3060 ($12 Amazon). I traced out my existing China wall gaskets onto the thinner (.060” or .12”) sheets and after cutting them to fit, I used some brake cleaner to clean the China wall surfaces and then sprayed the new gaskets with some spray adhesive. I allowed the glue to setup and then retested the intake fit.
The sides of the intake now sit down on the side gaskets flush and my gaps on the China walls are now .02”-.03” instead of previously about .09”-.11”. When I am ready for the intake install, I will still use sealant in these areas, but there will be much less area to fill. The adhesive will keep the gaskets in place while bolting on the intake.
Thanks for this post as it helped me out over the weekend.
