I am installing my systemax intake and want to know if I need to put any silicone on the intake gaskets. The thing is that it is mounting to stock heads and I am using stock gaskets therefore the crush ring on the stock gaskets may not be crushed since the intake ports are so big. I checked with Holley to make sure that I can use these gaskets and they said that it would be OK but I am worried about it leaking. What do you think?
