Not impressed

Comments about Mr. Gasket Ultra Seal; Intake Gasket:

the front and rear rubber gaskets are useless because they do not fit the block well, are spongy, and consequently just eject themselves when you tighten down the intake manifold. (felpro rubber gaskets are much better with respect to fitment and material). Also, the fiber gaskets are not even cut to accept them.

      Comments about Mr. Gasket Ultra Seal; Intake Gasket:

      Bought these for my modified SBC which these are advertised for. Would not fit the heads, stuck way out from under the intake on all sides. I would have needed to trim the bottom edge to get it to clear the head gaskets and block. So I returned them and purchased a different brand which fit right on no trimming needed.

        Even though this came up as being listed for a 1955 Chevy, it does not fit properly and will not work. This is for a later model car.
