Lightly buff the head and the manifold with the 3M pads you use on the angle die grinder. Check for flattness, add a thin layer off copper RTV. No gasket!

Mr Gasket Ultra-Seal gaskets are used.
The head pipe to manifold gaskets are typical Fel-Pro...but like I said...I am running a SPACER to get the damn pipe off the underbody....I took the spacer and RTV'd the two gaskets to it when I installed this engine last summer.
I had those same gaskets on my 440-6 mine made the same noise or close to it. I had to tighten them up over and over. Then someone said to run my manifolds without gaskets, that they came that way from the factory.
I wasn't sure if that was true or not, but I pulled mine off and went without gaskets on the pass side. No more noise.
Yr one has a seperate part number for the 440-6 head pipes. Mine went on without any problems. They cost like 106 each.
In 70 there is a different part number for one of the manifolds. I got mine off of a 70 challenger six pack. The flange had a different twist to it rather than the b body 69 stuff.
sounds like a exh leak, id get the surface straight and then put them on without a gasket as mentioned above..
the seal quite well without a gasket on the exh manifolds

No gasket is needed with stock manifolds. Prepare the manifold sealing surface with a 12 in flat mill file to remove any high spots or garbage left on it. I would take the manifold to a muffler shop and hve them braze the shaft holes for the hear riser if you are not going to use it. Clean the head sealing surface and bolt it up.

You know, these Mr Gasket gaskets don't line up well at all with the ports. Their port openinga are too large. There is very little coverage at all at the Tops of the ports.
When talking "no gasket", is it generally agreed that I should use a "a little" copper RTV applied to the manifold prior to bolting up?
and I am assuming that Headpipe to manifold gasket(s) are required. I don't go "no gasket here, do I?
I have found that most of the brands of copper header flange gaskets do not line up with the ports, most of them have holes that are too big - this is a problem with a small-primary header, but should not be as big a deal with a manifold. Can't comment on fiber gaskets, haven't used any for 15 years but OEM-sized gaskets should be OK?
I have had good luck installign manifolds with no gaskets or RTV. I'd say the copper RTV is optional, if you have some on-hand give it a try, you've already had the manifold off so it's a 20-min job to R&R it. If you still have a leak give the RTV a try.
Parts I seek:
driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set
16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better.
69-73 C-body caliper brackets and/or splashields
Send a PM.

I just went to Summit and here is how they list:
Fel-Pro
Port Ht 1.33
Port Width 1.84
Ultra Seal
Ht 1.48
Wt 1.78
That's a pretty substantial difference in height. These Mr Gasket port holes seem too large in the height direction when laying them down on the stock manifold. There was almost NO material covering the top of all of the ports at all. You can see the carbon lines on the manifold along the tops of each port....and it's right at (or maybe past!) the edge of the ports. Not Good.
BTW: I have used this mani for 5 or 6 years....this is really the first time I've had serious issues with it. Laying a straight edge over the ports, it sure seems pretty straight to me. I didnt get the feeler gauges out, but eyeing it up, I can't say this POS is warped to a point that it wouldn't give me a decent seal.

the ultra seals are a HEADER gasket to be used more for ported heads .
Yes I was talking about that perforated steel looking gaskets .
forget the straight edge put it on a flat surface and have a light behind it so you will be able to see light under it if it's lifter off the surface , will be most noticable under the center of it .
what heads are you using ? you gasket should fit the manifold opening , what is the size of the actual port on the head ?
