Hey Guys, We are putting a 1970 340 4 barrle intake on my dads 69 Dart GT. Do you guys use the cork gaskets for the intake or just use silicone on the ends? I have heard it both ways. I have always used silicone. I was just wondering what most of you do? Thanks Scott!

I agree, don't use the gaskets, but I prefer to use Right Stuff.

Yes,the "right stuff" is the cats [Edited by Moparts - Keep it clean]....

Definitely NOT a fan of any form of "gaskets in a tube"; I have never had much success with it; and I've disassembled so many things where the previous "mechanic" thought they needed a whole tube on say a thermostat housing; and then they wonder why they either overheat (globbed up/restricting flow) or never heat up (gets stuck in a t stat and holds them open)

I know that an intake is a little different, but I just use that as an example. I believe in using the correct gasket for the application. I ONLY use RTV in the corners where the side gaskets and the end seals meet.
As far as the end seals being "too thick" I can see that as being a problem when you've had a lot of milling done; otherwise,use the end seals that come with the intake gasket set, and something like Weatherstrip adhesive to hold the cork seals in place so they don't slide out on you as you set the intake in a little RTV in the corners and be done with it.

with volaredon,I use alittle rtv in the corners and shome copper spray tac on the cork

I let it cure up 15 mins then set the intake,watching the ends as it torques down,going slow and feeling with fingers keeping the cork from sliding out,kinda push it backin if its wanting to slide out,but thats very seldom

remove the 2 locating pins in the block if they are in,could hold the intake up and not let it seal correctly

I like the indian head shelc also for gaskets,hard to clean later but seals great

I glue the intake gaskets to the heads with gasket tack, then I lay a thick bead of Ultra RTV in the spray cheeze tube, cheaper than Right Stuff and pretty much the same.

Works great.

I've used Ultra Copper on orange painted engines so it blends in.

I use the OE mopar paper type gaskets with the foam ends. They squish better then the cork. I too don`t like the use of silicone sealer for the ends. I only use 4 dabs in the corners. Never had a leak yet. BTW, if you you the cork ends, don`t put silicone sealer on them or they will squish out for sure. Mike

I agree with the exception that I couldn't use the
end seals and had to use silicone with the
performer rpm intake I used because of the fit.
I'd have rather used stock seals for sure.
Friend at a radiator shop claims half of their
fixes are for crap from sealers stuck in the tubes.

I like using the end seals myself. I have seen many people missing the small roll pins that go into the block midway across. This helps retain the gaskets. The less silicone the better.

No kidding, has caused me to cut my use by at least
half!

I always use silicone and never have a problem. Just do it the way youve always done it.

The trick with the "right stuff" is apply a nice fat bead front/rear on the block set the intake in place tighten it down,and let it sit over night..before starting the motor up,works everytime

I used the factory style ends also and no leaks. I do remove the roll pins and in their place I put a piece of wooden skewer/kabob stick. Make it just long enough to hold the end gasket in place. The difference is these will colapse and not hold up the intake when it is torqued down.
