Fel-Pro used to be kind of the standard of the industry. But I haven't used them in years. They are probably ok for modern engines, but I don't drive modern vehicles long enough to need gaskets. And I buy my gaskets for Cummins from Cummins. Best specializes in vintage engines. Fel-Pro is owned by Federal Mogul, markets through places like Auto Zone and O'Riley which puts them in the same category of Chinese knock offs. The last Best gasket set I bought for a GMC was just like what I used back in the 50's.
