1966 390HP intake gaskets, front and rear

[Jerry C.]

Should the front and rear gasket have the GM tabs on them and if so would the small block gaskets work? If not where would find a set? Thanks in advance.

Yes, original end gaskets had the "GM" logo on the tab. Small block gaskets absolutely will not work on a big block.

Where to get them? The only place I know of is original NOS GM gasket sets. Of course, it's possible there are reproductions now but, to be legal, they would have to be done through the GM Restoration Parts Program.

I purchased a set from LICS, they worked fine. They had Fel Pro sides and reproduction ends.
