Do I use the stock manifold gasket with the iso thermal gasket or just the iso thermal gasket by itself?

Thanks in advance.

I have the same question. I believe u use both stock plus the one that comes with the kit.

 

heres how mine goes, the very bottom UNDER lower plenum, it says REPLACE gasket with iso thermal, then on lower plenum u RETAIN same gasket, then spacer, then gasket that CAME with kit, then top plenum, screw on, done

 

We have a winner!

 

Thanks people

 

Reading instructions is crucial

 

if you ordered them from Motordyne, they may send you two. You can use both of the ones they send you together, but you toss your old stock gasket into the "parts" section of your garage
