Intake Gaskets??

[TylerCharger69]

Okay...440 engine. Question is....are there supposed to be gaskets on the underside and upper side of the valley pan??  I've heard this around the forum before and this is the reason I'm asking and if so....can someone post pics??

OK here we go....yes and no some just use a naked valley pan, I did on my six pack and it didn't seal proper. They make gaskets in different thickness to adjust for variables like how much your heads have been cut and such. Really You need to check the long block as an assembly because heads, gasket choice, intake used ect will tell you exactly what you need at that point buy test fitting and gauging the gap. So plan on doing some "checking" at that point of reassembly.

Hmmmm....okay...I'll have to be meticulous and keep that in mind then.  But....did they come with them out of the factory, or was the valley pan just....as you put it....naked?  Anyone who may have pics....please post them.  Thank you for your input b5blue...every little bit helps!!!

Chrysler never fitted gaskets, just the valley pan.
I read somewhere that sealing problems started with the original ally 6 pack manifolds made by Edelbrock and Felpro introduced the gaskets to solve the problem.
I have never had any problems using the gaskets but did have a leak when I used just the valley pan. May have been just bad luck because there's plenty of intakes fitted without the gaskets and they don't leak.

Okay....so if I understand correctly....If I use the stock intake, then just the valley pan would suffice, providing that the surface of the heads aren't cut too much to cause port misalignment.  And I should consider adding gaskets if I were to use an aftermarket intake.  I have a 383 right now, and I haven't had any leak issues when changing the valley pan.  I wasn't sure if the 440 HP was any different or not.  At this point, I'm building the engine and haven't decided whether or not to use the stock intake, go with an aftermarket, maybe a dual quad, or a six-pack.  Oh....decisions...decisions!!!

i have never used gaskets on the valley pan with stock heads & intake , all i do is just put a thin bead of rtv  on each side & torque it down
   aftermarket heads & intakes yes  i have used gaskets  with & with out RTV

See what I meant....just remember head gaskets come in different thickness also, is the block going to be decked, are the heads cut, yada yada yada. When you build whatever you decide all this will fall in line as you go no matter what you have. Get a MoPar B RB Performance book and just start reading up on what CAN do and HAVE FUN!!

i use just the vally pan with ford powerstroke diesel silicone. that stuff is the shit when it comes to rtv! serious performance rtv, oil and fuel will not break it down and it is not thin and gooy like most rtv's. its thick like a paste and seals excellent. i use it for everyting from cars to trucks, oil pans to rear diff covers, even use it on the house for roof's and sealing seams. it is an awesome product.
