Guys over the years I have tried all kinds of gasket materials, fastners and sealents to keep my vavle covers tight and to not leak I have not had much luck..SO what gaskets etc do you use,...Its time to replace them again on my engine.

any quality brand gasket works, i've many different brands over the years. with good prep, and good sealant (i use orange silicone) and being careful to resist the urge to over tighten any good gasket will work even old fashion cork ones!

I've had the best success with the Fel-Pro black rubber ones. I torque them down to about 50-60 inch pounds repeatedly over the course of the first 10 or so engine runs--eventually they firm up nicely and seal real well.

I've had good luck with the FelPro cork gaskets; I glue them to the covers and then smear a little grease at the head side. Double-check the fasteners after a week. Make sure your covers are straight, of course. On a car with the HP exhaust manifolds, I've found that they get baked pretty hard after a couple of years, so I keep an eye on them but they still seal. No problems so far with Maxie exhaust or cars with headers.

Felpro rubber/cork has worked best for me.

mr gasket rubber cork work fine and are affordable. i currently use the moroso blue thats metal reinforced. i relly think there going to last for ever. had the covers on and off several times and they still look as new as the day i put them on.

none




I dont have BB anymore..

Moroso blue or Fitzgerald w/metal core(still in biz?). Much better than all the others and worth the cost.

We run the Mr Gasket Ultras.Mine have been off to check the valves and still seal.Even with the MP aluminum covers they seal.Run them on all the cars.Rocky

Moroso blue or Fitzgerald w/metal core


These are the only ones that will stand up the heat and not leak for years.....

Do the Moroso gaskets work on stock heads and covers? I tried the Felpro 1612s(rubber over fiber) and leak at #7 somewhere. Looks like the leak is between head and gasket, dry between cover and gasket.

Mopar red rubber. RTV it to the valve covers over night. Makes install so much neater and easier.

I think like was said earlier a good straight cover is more important than the gasket.

On my aluminum head/aluminum cover I'm just using cork that I had applied a light coat of grease to both sides for placement and have been dry as a bone so far.
I have even had the covers on and off a few times all ready due to the solid cam I run to watch/set lash

My brothers small block has some cheapy chrome jobs and we can't get them to stop leaking after MANY gaskets and goo's.
