GM '66 intake manifold gaskets 327

[Ian S.]

Hello,

Does GM currently offer intake manifold gaskets that are correct for judging with the tabs for 327/300hp?

Thanks,
Ian

No, they don't. Paragon has side gaskets with the tab, but I'm not aware of any regular source for the rubber end seals with "GM" on them.

Jim Gregg, a sometimes poster on here did have a few sets.

Thanks for the info. Are there any issues with using an NOS set related to them aging and not working properly?

Not usually any problem. If there is a problem due to poor storage conditions, it will be more-or-less obvious. Plus, if there is a problem, it will almost always be with the side gaskets and not the end seals. In that case, use the end seals from the NOS set with the Paragon side gaskets.

Paragon side gaskets. The camel hump has a verticle rib in it. Need to massage the rib. Make it go away. Very easy to do with a vise or small hammer. JD
