About silikonet gaskets

Hello!

To start with, i live in sweden where we dont have the same produkts in the shelf as you guys.

I have a 69 plymouth valiant With a 318 magnum, been hassling with megasquirt but finally gave up and order a speed master intake and edelbrock 1405,

Today I buy liquid gasket for the intake, thinking about using it together with cork gaskets in front and back.
I could only find permatex ultra grey (super grey) would that be sufficient?
My other alternative is Chinese liquid gasket under Swedish brand……

Best regards Will from Sweden.
I wouldn’t use both on the front and back under the intake.
Always had great results using only the RTV and getting the intake on immediately.
Set the intake on and see what the gap is, then put a bead of RTV higher than that.
