Username Post: Original Valve Cover Question???        (Topic#353793)

Greetings All:
On our 1984 Corvette, Original engine, the original valve covers are cast aluminum. The New Fel-Pro Perma Dry gaskets came with metal spreaders for under the bolts.Due to shape of covers, unable to use the spreaders because casting raises bolts up a bit off the actual surface of the valve cover. Since we are switching over to studs instead of bolts for cover, will this non use of spreaders be an issue? Also, Fel-Pro states install gaskets DRY, no sealant of any kind.
As always, Thanks in advance for your help.
Regards: Willow

Shouldn't have an issue. The original cast valve cover didn't use spreaders so you shouldn't need them now, studs or bolts. Cast covers are generally more rigid than say stamped steel covers...where the spreaders may be needed depending on thickness of the material used.

I ALWAYS! glue the valve cover gaskets to the cover on a small block. If they ever start to leak, which they all do after years of service, they are much easier to scrape off of the valve covers than the head.

I do recommend silicone on this application. Just make sure your silicone is completely dry before you install the covers.

If you put them on wet, it lubricates the surface, and makes it slide out. It always slides out in the back where you can't get to it.

Just my two pennies. Feel free to ignore.

Better yet on a cast valve cover, use contact cement. No need to wait on silicone to set up. The contact cement sets right now.

Is anything necessary? I know when I'm replacing something the last thing I want to do is struggle to get old gasket off of some surface.

If "Fel-Pro states install gaskets DRY, no sealant of any kind." I would believe them and install them DRY with no sealant of any kind.

Always worked for me.
