No probs with these at all.









If you find that nothing works, use Permatex Great Stuff (???). I use that on problem tranny pans immersed in oil with never a leak.
I agree. I used these on my 69 small block and stopped the leaks. No sealer, just the gasket. Works great. I did have to do a little hammer and dolly work on the valve covers to straighten them up where Bubba cranked them down way too tight!

Mr Gasket makes one thats kind of a rubber coated steel, nicest one Ive ever used. Will NEVER leak and can be reused plenty. They fit absolutely perfect.
Fel Pros are good, these are the #$it. Oreillys has them.

Motorhead, those Felpros shown by noonie and first links are the ones I'm using on my AFR's. I did grind a little radius trough at the rear corners so that the oil would not pool on the little ledge but even with cork they would still leak. These gaskets are perfect.

Rich,
thanks the Fel Pros shown are small block only per PN#
I'm going to use Fel Pro's PN# in BB application. Blue
Thanks everyone, again I learned allot.

I've had motors you could run with valve covers off with high rail heads.
not crazy about my Dart heads but do love that high rail feature.

I found if you use studs and nuts
that gasket will sit perfect every time and eliminate the need for any sealant
Who cares about correct if it doesnt leak lol.

You never need sealant
Cork has never leaked (I used the thicker cork ones by Mr Gasket)
Now using a Mr Gasket which imo is the best ever. steel shim with some type of rubber coating. Fantastic, had them on and off 1/2 dozen times already.

Get rid of the nuts, use spreaders or get a valve cover with a thicker flange. Factory stamped stuff always tweaks easy.
