Valve Cover Gaskets

What is the best non-leaking valve cover gasket? Type and brand?

I have the Cometic vc gaskets on mine. Have held up great. No leaks in 2 years. The previous FRPP/FelPro (steel core w cork on each side) gaskets were decent when new, but after a few times removed top run valve they leaked and were getting torn up.

Thank you, I forgot about Cometic.

Does Felpro not make the rubber ones for the 460?

Summit has a shit ton of Trick Flow rubber gaskets in their clearance section (Tallmadge).

Get the Cometic ones they are da bomb!

I had a set of cometics once , I'm sure they work well in some applications but they weren't so great with the tall ford racing valve covers , those covers have little raised up round things on the bottom and the cometic gaskets are hard and don't compress well causing a leak , that's just my experience with them

yep, I run mine over a big belt sander to get that and the "Taiwan"lettering off.I also had a little groove in a vc rail cause a problem with the cometics but after a few heat cycles it sealed up.

Cometics need a thick billet rail and need to be flat and smooth. ive got some flatouts here that are badass.... But they aint cheap either.

Thanks guys for all the info and Happy Holidays!!

The Cometic stuff is the best....unless the valve covers sux.

They show them in the Summit Catalog FEL-1617,i've always had good luck with the rubber Fel-Pros.

Were they for 429-460 and what day were you there?I might have to stop there on Monday and see if they still have some.

Thanks.

I'm like Jason when I have the good fortune of being in that area.I head straight for the corner of the store where the returns and discontinued items are.

I use the Moroso silicone gaskets with the steel core, love'em.

For valve covers which are not absolutely flat ...
I use the Fel-Pro 5/16" thick gaskets with the sandwiched metal support.

Yes 460. I was there several times in Dec and they had 3 boxes full of them.

I was there on Monday i found 1 set they were $16.00,i didn't buy them spent to much money on a cat back exhaust for the daily driver truck.

Just one set?


ne set?

With my valve covers and where my master cylinder is located, it is not possible to get a bolt in the lower rear driver side. Obviously I had a leak issue. Tried several different gaskets (not the cometics though) and I was suggested to try doubling up cheap Felpro cork gaskets. Glue two together to make one soft, thick gasket. Has worked out very well for me.
