The cometic/TA steel core rubber gasket is only designed to be used on Cast aluminum covers. Had a customer try them on his stamped covers when they first came out, they leaked right in the middle on the bottom.. the cover bends before you can put enough force on them to compress them properly so they seal.
For Stamped steel covers I have had the best luck with the new Edelbrock 7546. First cork/rubber gasket I have ever installed dry, and had them not leak. Next choice would be any of the TA or Fel Pro cork gaskets, with sealer.

These gaskets work great so far. I wasn't sure about them when ordering, but glad I did.
Update.... So the gaskets sealed, but only for a very short amount of time. I went to re-tighten the valve covers and they were slightly loose. I tightened down again, but unfortunately oil is still leaking. I'm not sure if the material heated up and took the form of the tight covers or if the bolts backed off. I'm just mentioning my experience. And to be fair to the product, I'm trying these on Edelbrock E-210 heads. Not factory heads. I read some reviews of people having a hard time sealing up these heads at the valve covers. Anyway, I'm trying a different brand of gasket. I'm keeping the 5 stars because I did like the gaskets and I'm not 100% sure if it's the heads causing my issue. Don't use on Edelbrock E-210 heads. Thank you!
