Who sells intake gaskets that are dead right or close? I thought I was happy with the Victors, but found an original one from an old teardown in a storage bin yesterday and saw some obvious differences that I should've noticed before.

Re: correct intake gaskets for '63??
The repro's from Paragon are close, and can be made better with a small modification to eliminate the line thru the hump. At this time, NOS is the only avenue for correct end gaskets.Bill Clupper #618 -
Re: correct intake gaskets for '63??
NOrris, THe big time judges really check for the correct end rubber gasket. SHould have a tab sticking out like Bill said. Tab has GM on it. They look at the front one and then fill behind the intake for the tab on the rear gasket. Meanwhile the repros camel hump is close but needs to be massaged to work. For my 63 show car we used a NOS set of intake gaskets and it sure paid off.

Re: correct intake gaskets for '63??
John,
Since you have a fuelie, are you talking about the gaskets, which go under the mounting plate, onto which the doghouse mounts ?
Those gaskets are different than the carburator intake ones, as you know.
The reason I am jumping in here is, I had to take off my mounting plate, due to the plenum still rocking when setting it on the plate, after machining.
When setting the plenum down, (3) pads looked pretty good, but one had a gap of .010 to .020". I removed the mtg plate, checked it in its free state, and it was still bad.
I will have the (4) pads re-qualified tonight and will also adress the bankface seal surface.
This leads me to the gasket, you are talking about.
I bought the gaskets from Paragon, they are shaped like the original ones, but I was not impressed with how the gasket fell apart when taking it off the engine, after only 1/2 hour of engine time. (I used permatex on the water ports, on both sides of the gasket)
I dont think the last gasket was this fragile. So I am also looking for the better gasket. Where did you buy your gaskets ?

Re: correct intake gaskets for '63??
I'm working on one of my 340 horse cars right now, but the fuelie response makes me wonder.................. what did I put on my fuel car when I set the unit about 12 or 15 years ago? It's never been fired but there's no telling what's under it, and now I'm wondering about the between the plate and unit seal. Maybe I'll just let it sit for another 20 and let the heirs worry about it. Does Podell warrant his unit resto's to fire after 30 or so years of sittin' with no fuel???????Comment

Re: correct intake gaskets for '63??
Ranier, Technically vendors, etc. are not supposed to be selling parts here. I realize that a lot try or imply though. Maybe someday NCRS DB will have some separate catagories like say VH. One category could be titled. Dumb Questions.
Another could be titled parts for sale and wanted. Then there could be one category just for cams. (heeeee) Duke's Corner they could call it.
Sorry old friend. You don't deserve this. I know of many hundreds of people that have used Paragons repro gaskets with no problems. Meanwhile they are NOT repros. Got one in front of the screen.Logo on the gasket is VR with a circle. I assume that is Victor. Anyhow Victor 15315. Then the Victor gasket is cut to somewhat match the originals. Many years ago at a seminar Dr. Mike McCagh showed us how to massage this gasket. He put the camel hump in a vise and flattened out the verticle rib. I just use a ball peen hammer. The long gaskets are pretty nice. The end rubbers though I never liked as its too easy to have major leaks.
I am sure you could go to your local auto store or even Chevy and get a nice gasket. Maybe Joe Lucia or Duke can chirp in with some recommendations.
For my show car I got my gaskets from the Drive Line. NOS with the correct end rubbers with the tabs. The tab thing is one of the judges nitches. One of the things they look for. JohnComment

Re: correct intake gaskets for '63??
John-----
As far as correct intake manifold SIDE GASKETS, the Paragon reproduction is as close as anything you can get today, except for NOS.
As far as the end seals go, the Paragon gasket kit is not 100% correct since the tabs lack the tiny, embossed "GM" logo. As far as I know, no one reproduces these end gaskets. However, if one can find ANY NOS gasket set for a pre-1969 small block, it will have the GM-embossed end gaskets. So, even though the side gaskets might not be correct, the end gaskets should be. By combining the side gaskets from Paragon with end seals from ANY pre-1969 GM gasket set, one should have what one seeks.
One cannot use a 1969 or later small block gasket set as a "donor" for the end seals for a pre-1969 application. That's because the end seals changed for the 1969 model year. Pre-1969 used end seals with "side tabs" for block location. 1969 and later use "dowels" for block location. The 1969 and later GM gaskets do still have the tiny "GM" logo on them, though.In Appreciation of John HinckleyComment

Re: correct intake gaskets for '63??
Joe, You are correct. Nothing wrong with the side gaskets. You just have to flatten out the rib on the hump so to speak and maybe play with the camel hump top a tad. Trying to find the NOS ends those isn't easy. My 63 NOS old old gasket set had the front seal that was quite large and had a round hole for the oil filler tube. So the seal went the whole way around the tube. Jorjorian said these are rare. Then you see two different fonts of GM. Large print and smaller print. I believe the one on my 63 had the larger type. Course your can't see it anyhow.
Oops. Sorry. Just scrolled up and reread your last few lines. I see what you mean and understand the mystery now. So the small GM logo is 69 and up. Thanks. Learned something new. One other thing.
One thing guys have to be careful with for sure is not using the old 265-283 gaskets on the 327's. Some buy those sets just because they have the end GM Tabs. A few years ago I laid a NOS set of those on a set of 421's and said wow no wonder my customer is having problems. Much too small. Thanks, JohnComment
