As of late, I'm hearing of others who have had issues with Felpro, and raving of 1st, Victor Reinz #MS15166X, but heard it's no longer available. Jay Brown suggests these below.
MAHLE Original MS15166X Engine Intake Manifold Gasket Set.
The cost I've seen is apx $15 to $20, but Rock Auto is the lowest of $5.00.

2nd is Mr. Gasket 202A.
Another mention is by SCE,.....Accu Seal Pro Intake Gaskets.
Accu Seal Pro Intake Gaskets for 390-428ci Ford FE; 234103 | | SCE Gaskets
I'm looking for intake, timing cover, water pump etc, to finish my 428FE build, so that's why I posted these links and info.
