Install intake manifold on 440

[WVUFELLA]

I was reading a post back in april and i just want to clerify somethin. As i read it said that installing the valley pan that some people dont use the cardboard/ paper gaskets at all.  Thye just use the valley pan and that is it. Is this correct?? I thought you put a paper gasket  on head .... then put the valley pan .... then another cardboard /paper gasket on top intake.... then put intake down and tighten down.... SO if you saw a cross section it  wouold be intake manifold/gasket/valley pan/ gasket/cyl head.   Maybe i have been doing this all wrong. Could someone verify if this is right  maybe i read to far into it or somethin ??

the way you are doing it is correct , I generally just use the paper side gaskets between the head & pan & silicone between the pan & intake , often it is very difficult to get the intake on with the added thickness using both side gaskets ,it can also be done with no side gaskets as well , this is the way the factory did it

yes it does take alot more to fool with the bolts. I guess without that extra gasket it would give you more clearance. However not using those gaskets give you more fo a chance for a vac leak wouldnt it??

Yes , oil or vacuum leaks

I never use the paper gaskets, never any leaks.

I just use Gasgasinch on both sides of the valley pan, then use RTV on the front and rear part where the steel hold down bars run. No leaks.

in rare cases I have seen oill sucked up into the intake but more likely due to intakes that were milled at the wrong angle , generally you willnot have an intake leak just using the pan

I tried both paper gaskets on my 440 and it was so tight I cross threaded a bolt and stripped out the head. Put a heli-coil in the head (worked great) and tried with one paper gasket. Tight fit but it worked. In the past I've used no paper gaskets with no problem. I also used gasgacinch. Next time I will fit everything up dry (sans sealer) and go with whatever fits the best.
