Default Valve cover gaskets

Has anyone used the FelPro Perma Dry Plus gaskets? Are they worth the premium price? My right valve cover has an annoying leak at the bottom rear. I have used a cork gasket & Permatex but it does not seem to last more than a few months. Any input will be welcomed.

Thanks for the prompt response. Have you used the gaskets for the valve cover or the intake manifold?

I have used these for the last year now. I only used sealant on the cover side. Nothing on the head. Allows me to remove and put back on with any problems or leaks.

EXACTLY! And be sure to tap down the bulges around thebolt holes in the valve covers from being overtightened to compensate for leaks.

The 'primo' valve cover gaskets are worth the price...IF you need to pull those covers regularly. But, if you just want to seal them up, buy the Fel-Pro composition gaskets (cork & rubber) and use sealant between the gasket and the covers. Then, wipe the mating surfaces of the heads off with lacquer thinner or other solvent and install the cover/gasket assemblies using correct bolt torque, applied in stages (1/3, 2/3, & full torque). Unless you have a chipped edge on a mating surface of one of the heads, they won't leak. (And, you can still remove them, if needed.)

Something like this,

can go a long way toward avoiding distortion of the valve cover flange. They spread the pressure out over the gasket area. Don't over tighten.

Default 3M trim cement {yellow or black}

Either one are good choices...As suggested above by a few members, only the vqlve cover gets gets the cement and as it gets tacky after a few minutes lay the gasket to the valve cover held securely by most any objects until it drys solid {about a 1/2 hour}.....The gasket will not be affected by rockers or anything else under there...as some engines have interference items hid under the covers,,,they won't get bumped causing a leak you can't see...and .for the head surface some wheel bearing grease is all that's needed

A Hint, don't use those silicone sealers for valve covers ...BIG mistake

I use spreaders on each bolt, longest ones I could find, stamped valve covers and feel pro gaskets. No leaks. Valve covers go on and off over time so wouldn't want to use any kind of glue.
I've had mine on and off at least 5 times, still no leaks.

This is what I have used to prevent the sealant from hardening over time. After applying I would let it sit for 15 minutes before I tighten the cover down. Then let it sit for 24 hours before running. After that you can remove and re-install as you please.

I got tired of leaky valve covers so I bought the Fel-Pro Molded Silicone Rubber gaskets (part #1628 for a small block). They are a little pricey but I have yet to hear of anyone having a leak issue after using them. They require no sealent and they are reusable. They also have stainless steel compression limiters to prevent overtightening.
