Oldsmobile 307 roller engine valve cover gaskets

[AlexW121]

Hi there. Looking for some help in finding some valve cover gaskets for my 307 oldsmobile roller motor. The motor is a 1985 and yes, has the roller cam. Looks like it only has 5 bolt holes in the valve cover, but I can only find the common 10 bolt valve cover gaskets (photo below) was wondering if anyone has a specific part number for these, or if the 10 bolt gaskets also work on this ol 307. Thanks for the help

Yes, the 10 bolt will also work and are the only ones available. You can actually drill your 5 bolt covers for 10 bolts. I prefer this style of gasket.

8 lbs/ft, or 70 inch-lbs.

Factory only had 5 bolts. They didn't use gaskets from the factory. They used gasket making compound goo. The stuff dries up and cracks then subsequently leaks out 4 quarts a minute it seems when it does let go.

The gaskets you buy over the counter anywhere fit, however. And they will be 10-hole versions. You can get various brands that are cork, or rubber, or rubber with reinforcement in them, and fiber types too. I personally don't like non-reinforced cork as it squishes out pretty easy.
