Why the special valve cover gaskets

[Richter]

Hello all,
I’ve been chasing a vacuum leak for ever even though nothing externally has changed the issue, the oil consumption fuel mileage and low vacuum I decided to replace the intake gaskets ordered the felpro and saw the note that you have to use a specific valve cover gasket. Looking into it they all don’t require it and some come with grommets. I never really messed with the 3.0 so it has me confused. What’s the deal? I’m old and easily confused so be patient with me.

I get the impression that's just Fel-Pro trying to sell you the whole set of "PermaDry" gaskets.

They are highly regarded.

The ultra power requires the same and offers another alternative. I need valve cover gaskets either way but why those 2 say it has to be that gasket and where others offer the grommets and they don’t just had me confused. I was thinking for flex fuel or something else but I couldn’t find anything. I just don’t want to get it apart and end up waiting for parts to reassemble.
