valley pan,intake gasket question? - 04/29/11 09:23 PM

kinda dumb,but getting all my ducks in a row so to speak,changing from 4bbl to 6pk manifold,when ordering new felpro gaskets,i would want 2 pair,one i would think would go under valley pan,second on top? thanks

Why even bother with paper gaskets? They really aren't necessary. The tin is reusable a couple of times at least.

Re: valley pan,intake gasket question? - 04/29/11 09:29 PM

so i'm just wanting the intake gaskets to mount between the tin and manifold,right? just though there may have been a second gasket,similiar to oil pan,windage tray

You don't need paper gaskets at all. You just need a little RTV on the corners

If your heads have been milled or block decked you'll need at least one set of paper. I had to use one paper set on the old set-up.

Re: valley pan,intake gasket question? - 04/29/11 09:56 PM

That depends on whether or not the intake has been milled to match.

most times not needed,I do use the VP that has the heat cross over blocked with the alum intake and carb to keep the heat soak down.

rtv in the corners and across the end rails lightly.

the good part is,it is reusable a couple of times for fast intake/carb swaps.

some times the gaskets can be to thick,so check with member 'topside", he sells some thinner gaskets sets that are cheap and good quality.

member "road hazzard" has a nice brand of gaskets that he makes as well,great non-stick gasket compound,IIRC

congrats on your new 6-pak set up!

you will need tires soon

IF you take your time with the VP and install the intake with care ... you will NEVER have to buy another VP ...ever again.

That is IF you "glue" the papers onto the VP ...and then "Pam" the intake man and head surface. It will seal great and come apart smoothly.

The engineers at Mopar and Felpro came-up with those "papers" for a reason.

,thank you doc

Sorry Doc but the engineers at Mopar didn't have a thing to do with the paper gaskets. That was a felpro idea to make up for head height changes. I have bought a boatload of valley pans including felpro over the years that never came with paper gaskets.

That is not what I heard stumpy ..... it was due to alignment probs with the alum Eddy intake is the reason for the papers.

Doing the papers can be a PITA .... but it is worth-it.

Re: valley pan,intake gasket question? - 04/29/11 11:15 PM

Again Doc sorry but that is a nice story not reality.

Re: valley pan,intake gasket question? - 04/29/11 11:18 PM

....if that is not reality ... then why isn't there a VP and paper-kit for the B engine also ?

Re: valley pan,intake gasket question? - 04/29/11 11:29 PM

I can't answer that but as a line mecahnic for Mopar in the 60s and 70s I do know it wasn't a Chrysler deal.

Re: valley pan,intake gasket question? - 04/29/11 11:36 PM

I was never a line-mech ...what I know about that is from the guys at Highland Park and CTC.

And from what I know .. there were more std OEM alignment issues with the B-engine. The block deck-heights with the B-engine are famous for being way-off in left-field.

This subject gets beat to death

Doo a search , its been discussed a million times

However its funny how some say the paper gaskets are never needed

Really , that brand new Holley Street Dominator Intake that i installed about ten years ago almost cost me a motor - It was sucking oil so bad on the passenger side head intake ports because i failed to use the paper gaskets at all

However the Edelbrock Intakes that i installed didnt require the paper gaskets

If i was buying any intake , used , brand new , aluminum blah blah blah , i would let the intake dictate on whether i would bee using paper gaskets or not by test fitting , lining up the bolt holes etc.

Peace Scott

sorry Scott if my post bothers you,i haven't seen it a million times,and wanted input,what i did was order gaskets,if i need i have,if i don't i won't,as a weekend project,my plan is to get out in the garage,have everything i could need in reach,be cruising by evening,not wishing i had asked before starting my project,where you didn't and it almost cost you a motor,hence my post.

Thanks for the mention, Scratchn.
I figure 5 bucks per motor to be SURE I don't have to pull the intake back off to look for or fix a leak and then repaint the bolts is pretty cheap insurance; and at .015 thick, the intake isn't jacked up. That's why we made 'em, and we've never had a sealing problem since.

Doo a search function

I agree no papers.Its like wearing a belt and suspenders to hold your pants up.Ive run aluminum intakes and still do with just the tin.A dab of RTV in the 4 corners and i run a little under the pan where the hold downs go.Now on my 440 I have aluminum intake and heads.Just tin.Rocky

All felpro valley pans come with 4 gaskets in the kit , are you buying a new valley pan ? Otherwise when you order the gasket they come with 4 in the set. Members roadhazard and topside sells gaskets that are half as thick as the felpros, you may want to go that route if you find it hard to get in the bolts on one side after you have one side of bolts already installed.

It would be nice if some people would ACTUALLY answer the freaking question instead of TELLING and ARGUING you what you should do .

Re: valley pan,intake gasket question? - 04/30/11 01:41 PM

I guess I should have mentioned you should test fit the intake 1st no matter what. Some need paper some do not. It sucks to have you goop in place, pan in place, drop the intake an it doesn't fit and you have to run to the store for a $12 part. My brand new RPM (on an old build) had to be milled .030 to fit on a stock 906 headed 440. I think the rule of thumb is, lay the intake on if all te bolt holes line up use the pan only, anything else might require paper and or milling of the intake.

FWIW, after installing an Edelbrock Performer RPM intake, using just the valley pan, I had oil getting down in the cylinders. The intake fit just fine. Oil was getting sucked from the valley to the cylinders. I was told the oil problem was caused because of aluminum and iron expanding and contracting at different rates. Took it off, replaced the valley pan and added a paper gasket to each side. No more oil problem. Just saying.

Same here with a Weiand 8008. Added the paper and no more seepage.

You two are crazy , we have members that have reused the original valley they found in the trash for 50 years and one million miles and they never leaked ...

Got em all beat by using lower half of new or used standard gasket, then use paper to seal port areas on my freakish stage 6's.

Re: valley pan,intake gasket question? - 05/09/11 04:06 AM

Just went through this on my buds 68 Coronet RT Convert

Performer RPM Intake - Intake fit fine , valley pan only

Then tried two of the four gaskets supplied in kit
Still fit fine

Then tried all four gaskets - No go , bolt holes wouldnt line up

So i used the two gaskets on the head sides only

Works great - Couldnt of worked out any better
Like i stated in my first post , let the intake dictate gaskets or not - Especially on aftermarket aluminum intakes
