I agree with Dillcc,
I'm kinda confused by what you're asking but I'm going to assume that you was talking about the upper intake because you said "intake" but nothing about gaskets. And the LIM itself is already aluminum so it'* either the upper or the gaskets that you're asking about.
However if you was talking about the LIM gaskets, you want to go for the aluminum gaskets, dealers have them for approximately 50-70 bucks.
But will you clarify for us?
Gaskets or the Upper Intake?
