Those are new to me. work

I've used the "thick" Fel-Pro gaskets mentioned above, but like fast68plymouth mentioned, they delaminate (peel apart?) during the first disassembly.

If my standard Superformance VC gaskets have any sealing issues w/ Indy cast covers on Edelbrock Victor heads (something odd about the Victor's valve cover rail, as I recall from AndyF), then would the Carbon-X be your next suggestion?

If you have the Superformance #3186 Micropore-15 valve cover gaskets check and be sure the valve cover sealing surface is flat.
You won't have any issues.

?????

So if your valve covers are leaking at the "top" which is very unusual. Would there not be oil pooled on the cylinder head and intake manifold? Looking at your picture there is plenty of area for oil to pool on your (Victor?) heads.

Hood off or not, oil up by the timing cover might suggest your valley cover or possibly even your distributor is leaking. I don't know, I'm not there. "You" need to confirm exactly where the leak is coming from.
May not be the valve covers at all.

I will refer you to my previous comment....
"When someone purchases from Superformance Products they get real, honest and cohesive tech support direct from the manufacturer. Take advantage of that benefit."

The root cause of your problem could have been addressed with a simple phone call, sorry you didn't take advantage of that.

Thanks for your support

Bill, I would have suggested the #3186 Micropore-15 gaskets for your application, that's what they were made for.

The Carbon-X will work though.

As always, thanks for your support thumbs

You won't have any issues.

The issue isn't whether the cast valve cover flange and the cylinder head valve cover rail are both flat (they are), but an overhanging issue like I believe AndyF brought up previously.

When I put the MP-15 gasket on the valve cover, it's a pretty good match. When I put the same gasket on the head, it overhangs the intake-side of the valve cover rail noticeably, leaving only part of the gasket to seal on the head while the outer edge is covered up by the exposed lip of the underside of the valve cover flange.

This is an Edelbrock BB Victor design eff-up, but it is what it is. frown

Yep, when the cylinder head designer moves the rails the gasket mfg gets the blame!

I've probably said this a million times but "not everything works with everything". It isn't like there is an official Mopar aftermarket certification board that hands out stamps of approvals for Mopar parts. People just make stuff and sell it and maybe it fits and maybe it doesn't.

I'm not sure why a company like Edelbrock would change something fairly standard like the valve cover rail dimensions but they did. Or at least they did on the early Victor heads that I owned.

My personal way to deal with this stuff is to keep a large collection of gaskets on hand. Any time I'm working on new parts I check them against a stack of different gaskets to figure out which parts will work. I do not know any other way to figure it out. People don't put instructions in the box that say "we changed the dimensions on our part and your existing gaskets will not fit".

Maybe I just found another use for my Belzona: build out the valve cover rails to match the bleepin' covers. whistling

So what you are telling me is the gasket does not cover the whole flange on the cylinder head and there is exposed sealing area area?

I understand what is being said about the alignment of the valve cover flange in reference to the cylinder head flange not being in optimum alignment. If you had .125" or more of contact area where the valve cover and the cylinder head meet on the top sealing surface it should be enough to load the gasket and create a seal.
Now let's just say you only had .125" of good contact area between the valve cover and cylinder head along the top rail. If you "increase" the thickness of the gasket it will tend to roll/twist the gasket on that flange and give you the shear that Andy speaks of. More thickness and softer density will make the matter worse.

Can you set the gasket on the head, throw in some bolts for alignment and snap a pic or two of the flange area?

Another reason the MP cast covers can be difficult to seal with thinner, less compliant gaskets is there are irregularities cast into the sealing surface area.

Even if the covers aren't warped, the gasket surface isn't "flat"(smooth).

Brad, if you have a sharpie/marker, you could color up the upper v/c rail on the head, lay the gasket on it, and scribe a line of where the inner edge of the gasket sits.
After pulling the gasket off, you'd be able to see how much overlap there is.

ok, I found the extensive part of the oil leak. Was leaking from the valley pan directly under the intake. Pulled the cover, cleaned it up good and sealed it with the Right Stuff. Installed the cork valve cover gaskets, went for a power ride and no leaks. non, not even a drop. Cool, I'm sure happy with that cause this thing was leaving pools of oil on the cover.

You would be amazed at the amount of oil that slings off the cam and hits the bottom of the valley plate/ bathtub gasket!

Maybe the valve cover gaskets were not leaking after all but as we discussed over the phone, would be good to get them surfaced flat over the winter, put the original gaskets back on and roll with it.

Nice chatting with you Dave wave

Yes, will be a good winter to do. Get them machine flat would be the best thing. Your gasket may not have been the issue. Nice chatting with you as well Greg.

Again, I'm using MP covers that do not leak a drop after about 8 years and yes, the thin red ones. Silicon-ed to the covers on rpm heads.......... beer
