On a Sunday .
Part #RF11-003 /RF-11-001
I would suggest the 001.
As usual we show both on our web site and in stock.
Apparently most of the netters are not aware as the other s that are
on their own seem to find us and order.

Yes, I would too - until I had a failure - please read on.
I installed Dave's gaskets, and they cured my gasket problem for several years. Then last year I had a leak on the passenger side, and the manifold developed a crack from top to bottom. I got another manifold from some fellow in Kentucky, and I bought another gasket from Dave at Duquoin last fall. When I removed the manifold I found the bottom of the center section was almost completely gone (I will post pictures when I get a chance).
After removing two broken grade 8 bolts (that's a whole 'nuther story) and cleaning the head surface I used a straight edge to check it. The bottom edge of the opening was even, but the upper edge, above the double opening, was a bit high. This caused the gasket to have a slight gap at the bottom, and put a strain on the manifold, causing it to crack. I really did not want to pull the head to have it trued, so I chose to use the Remflex gasket on this side, along with a replacement manifold that had been milled flat. I will let you know how this works in a few thousand miles.
I still would recommend Dave Lenzi's all-copper gaskets because of better heat transmission - but the heads have to be in good shape. BTW, I did not change the gasket on the driver side, as it is still good. If it ain't broke, don't fix it.

Erv,
The primary reason why the bottom was leaking is in the dsign of the
bolting pattern.
Never tighten the top center bolt as it will tilt the unit and cause
leakage at the bottom
This holds true for headers .

J R;
Thanks For The Remflex Gasket Part #
Just pun in a Edelbrock Intake manifold with a plugged crossover & #404 MrGasket Set ~
Recored The Radiator, New Alternator, Fan Clutch, New Belts and Hoses thruout ~
When I cranked it up early this morning I found an exaust leak on the right side ~
Late this afternoon we Checked, Retorqued, Tightened everything, Let Run for 2 hours
We pulled a vacuum on the Dash A/C System eaelier and it held fast
So we recharged it with R 134-A freon ~
Soaked down right Side Header Bolts With P B Blaster real good this afternoon
and planning Tomorrow's installation of the Remflex RF-11-001 Exaust Gasket ~
Thanks Agan For The Number ~
~ Joe ~

We now also carry the New bigger Doug's headers that is a spiting
copy of the Thorly, but is for a 455 as it has bigger flange opening.
The late Joe Mondello helped me to be the Warehouse Dist. for it, now
you can acquire them from Jim Bounds,Jeff Sirum,Tom Hampton,Ken
Frye,Migil Mendez and Applied.
It will also come with an O2 bung on both sides standard.
Joe Mondello also had us set up as WD for the Pertronic ignition parts
which i will make available to the other GMC shops.
Our prices are better than Summit on the Pertronics.

Jim, I didn't tighten the top bolt when I installed Dave Lenzi's gasket. I re-torqued the other bolts several times per Dave's instructions, and the last time they wouldn't move at 25 ft/lbs. I still think it was the high spot on the head which caused the gasket failure.
When I removed the manifold the top bolt twisted off, and I didn't even bother to remove it. I also twisted off the rear two bolts, which were Bowmalloy (stronger than Grade 8 according to them) which brings up a rule which has been repeated several times on this Net - don't use grade 5 or 8 bolts for this as they are a PITA if they break off. Amen to that! BTW, when I installed these I had used anti-sieze, which was baked into the threads.
I tried several methods to remove these bolts, and nothing worked. I finally found out how to get them out by reading several car repair forums. Several guys mentioned using a cutting torch, as the torch won't cut cast iron. I ground them flush, and blew them out with the torch. However, I must have gotten the cast iron too hot and hardened it, as I had a heck of a time rethreading the block - but finally got 'er done. Broke off one tap, which I then removed with the cutting torch. I got ungraded bolts at the hardware, and installed then with anti-sieze. I torqued them to 15 ft/lbs per the Remflex instructions. We will see how these work out.
And to Gene - you wrote:
"When you all get tired of this hassle. Headers fix the problem"
Yep, I have to agree now, and that will be my next step if this doesn't hold. But I believe you are also the same guy that says "If you have good manifolds, use them. When they fail, put on headers". I have just been too stubborn to take that step, I guess.

Anti- seize and Kroil are you friends when working on those bolts. We have some industrial anti-seize rated at 2500 degrees at the airport. It works good on oxygen sensors and exhaust manifold bolts. I'll have to find out the brand on it.
I still recommend a 3/8" battery powered impact to remove those bolts without breaking them. Soak them with Kroil and wait a day. Then hit them with the impact wrench. If they do not come off easily, soak them again, and wait another day. Repeat as necessary for as many day as it takes. Usually this is somewhere between 3 and 5 days. It may take a while but you will not have any broken bolts.
