a few things you should know

Ive had the best luck with the extra thick synthetic /cork composite mix gaskets
(these gaskets, below)

[1] synthetic oil desolves that yellow 3m weatherstrip gasket adhesive than many guys use over a few months time so you cant use it to glue valve cover gaskets
[2]you must use a o2 safe gasket cement like the BLACK RTV silicone cement and you must clean and degrease the cover with acetone or a similar solvent before glueing on the gasket to get the best retention
[3]you need to allow at least a few hours to over night,depends mostly on temp. for that black silicone gasket cement to set up before installing the valve covers, and placeing them gasket side down on a table with a sheet of wax paper under them and a 20lb weight on top of each valve cover while the cement sets up is the best way to insure the gaskets stay correctly aligned on the valve covers perimeter
[4]a light coat of (PAM) cooking spray on the lower gasket surface keeps them from sticking to the cylinder heads after installation
[5] these gasket retaining rings add a great deal to the valve covers ability to firmly hold the gasket WITHOUT bending SHEET METAL VALVE COVERS OR CRACKING CAST ALUMINUM VALVE COVERS AND ARE WELL WORTH THE MINIMAL COST

[6]doing it correctly the first time saves time and money

I use Fel-Pro molded silicone rubber gaskets. They are made from high temp silicone rubber and have a solid steel core. They are reusable and they are the only gaskets I have found that don’t need to be tightened up all the time using factory original aluminum valve covers. There is no need to use any extra sealent with these gaskets. Jegs has them but they are way over priced from them. I ordered my set from a local parts house I have been dealing with for years for less then $30.00 3 years ago.

I grew tired of replacing rubber and cork gaskets on a regular basis on my 350 & 396 engines. I found that any reusable silicone gasket with a steel core will do the job extremely well, and leaks will be history. You can find them just about anywhere, and you do not have to buy the big dollar ones. They are thicker than any of the original replacements, but that was not an issue for me on a 79 350 L82 or 67 Chevelle SS396. Ken

Steel core rubber gaskets. Never had one leak, and you can use them over again.
