There should have been 2 blockoff pieces made of the same material in the box!!

If your pressed for time you could solder in a piece of sheet metal onto the valley pan to cover the heat riser opening(s). Just make sure you dont fab something too thick which'll hold the intake up. Not likely but just a heads up

Never seen one like that , I have that gasket and it's solid across the heat riser port.

I did, way back (decades) & I'm thinking it was Felpro but wouldn't swear to it and might not even be available
Yep! Felpro... I purchased one a couple of years ago from Napa. Could have been old stock?? But it did have 2 pieces that plugged the heatriser ports. 
i got one of those about 2-3 years ago, and the plates that come with the valley pan are way too thick. lucky my current heads don't have the heat crossover.

cut 2 pieces out of your old valley pan. It'd be the right thickness and the right material

(Jegs)...worked with Felpro and determined somehow that Felpro made a mistake and there are dozens of them out there like this!
I just ran into the same problem at Summit with a Zoom clutch kit. The model Zoom I ordered was supposed to be diagphram P.P. and I received a 3-finger. They opened all their inventory - same thing. Hat's off to Summit for immediately rectifying the problem no questions asked, but, it was an extra hassle I didn't need.

That was a Mickey Mouse deal offered through Mopar Perfomance some time back. Useless as titts on a bull.

Mike FelPro made them with the 2 pieces also.I had one and returned it and got the one with the blocks made into it.I even had one that had the plates made into it that came with the 2 pieces also in the package.They are probally laying around here somewhere.Rocky

I remember the... stuff it with 100$$ bills  I have always blocked it running an alum intake and run a heat disapater under the alum carbs on my SB I will do the same on the BB also it helps with heat soak and perking gas out of the eddie carbs/vapor lock cheap fuel today evaps fast and is more for a feul injected engine with high pressure I have just cut thin peices and used copper rtv to stick them in place,most gaskets that are block will burn thru in a short time but I have also used a whole tube of the copper rtv to fill the complet void in the intake passage one thing for sure,the copper rtv will not burn and seals up some warped headers real fast and ezy I am droping the BB intake by the welding shop at work to have the ports weld shut on my wieand intake this go round on another note...whats the opinions on that cross over in the intake was to eliminate the H-pipes in the exhst sytem that cars came with back in the day old timer mechanic said that mopar killed 2 birds with one stone adds heat for fast warm up and fuel atomazation and does the same thing the H-pipe did to = out/help scavage the back pressure/exhast pulse on #3 and #6 cyls or #4 and #5 cyls I know I can hear a differance in the glass packs tone/sound with it open or blocked idling at 850 rpms..closed has more deep tone and poping I think he is  but then again what do I know

I used one of the FelPro valley pans with the blocked crossover. That cost me a turbocharger. The little holes were stamped but not punched out. One of the little pieces blew out of the pan and into the exhaust. It ended up getting folded in half and shoved into a turbo jsut far enough to chew up the compressor wheel. Thanks FelPro!

I'm not saying the old guy's right on the reason, but he's right that there can be sound tuning effects.
Back when I was trying to solve some heatsoak problems, I tried a blocked crossover on one of my cars that has an X-pipe. At somewhere around 2500 rpm I got an **awfull** exhaust resonance, so bad that I could hardly drive the car thru the neighborhood. It only lasted a few hundred RPM, but it was loud, and sounded like 2 Hondas fighting inside a metal shed.  Should've videotaped it for posterity and youtube.

old timer mechanic said that mopar killed 2 birds with one stone
adds heat for fast warm up and fuel atomazation and does the same thing the H-pipe did to = out/help scavage the back pressure/exhast pulse on #3 and #6 cyls or #4 and #5 cyls
I know I can hear a differance in the glass packs tone/sound with it open or blocked idling at 850 rpms..closed has more deep tone and poping

I don't know about that because the 440 4bbl and 6pk cars in 70/71 had H pipes and the crossover in the intake .

If you run the car at all in cool weather or on the street I would leave it open. Cars run better warmer then too cold
If my Chally has Edelbrock Performer (not Performer RPM!) with headers, is 100% street driven in VA where it gets 95F in summer and only occasionally driven in 45F or below in autumn, should I block the crossover or not?

If you are not using the heat well choke thermostat for the choke i would , no matter what those chrysler engineers think .
On the other hand if you have a smog era smallblock and the intake has never been off you are all set as the chrysler engineers designed those engines with a self blocking heat riser port ...

I remember a thread where guys were discussing epoxy, aluminum foil, steel wool, who knows what else, on blocking the crossover.
I wish I could remember who said it, but it was along the lines of
'if you're gonna pack a bunch of stuff down in the crossover port, make sure to put $100 bills in there too, then when it breaks loose and gets down in a cylinder at least you'll have the $$ on-hand to fix it'...
I got feed up ordeing valley pans and getting the wrong one localy the crossover port is hour glass shaped so the epxoy can not fall in and last I checked my exhaust pushes gasses out never sucks in 
But if it does fail I promise you guys will be the first to know

I would think that if the heat rised is operating properly it's going to PUSH the gases from the restricted passenger side to the unrestricted drivers side .

I blocked the crossover passage way in the intake with JB Weld, more than 10 years ago. It is still there and that intake has probably 75k mile on it now, it was my DD for 5+ years.
They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

Those d#mn Chrysler engineers didn't know what they were doing when they left all those crossover's open.Look at the millions of motors they screwed up.  :whistling
The engineers were just making a compromise to appease the masses, the average buying public, which we are not.
It made for a car with quicker/better warm-up manners, many sales would have been lost if Chrysler got a reputation for running poorly when cold.
A slight decrease in power was the penalty, which the masses were far less likely to notice.
Much like soft-shifts in an automatic, super light power steering, and soft suspensions-the buying public equated that with quality---the owners 40 years later? Not so much!

IMo, it's got a lot more to do with a correctly fucntioning cold environment starting system than any other reason. The crossover function has nothing to do with engine operating temp. It lets the choke pull off faster and apparently there wasn't enough power lost through heating the plenum base to make it not a good idea for the factory. But once an engine is no longer stock I see no reason for it. You can simply re-set the choke if you stay with a factory one, or remove it entirely with little fanfare. JMO anyway. I drove my 6bbl car with no choke all winter for a couple years. Freezing cold starts meant I had to feather the gas for about 10 seconds. This car had 7" of idle vacuum and was not really close to stock.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

And that's the prob as it gets way too hot but I agree w Paul if mileage is a concern (not usually w a 440 
) the heat riser helps and pretty sure that's what's killing mileage on my 318 DD.
