If so, Tony, was it (OEM gasket) supposed to be removed and replaced with the one you supply? Ashamed to say that I still haven't installed mine. Trying to have other work completed (fine touches) before moving on to the next step. Getting very excited.

 

Yes. Remove the "Manifold" gasket and toss it. Replace with Iso Thermal Gasket.

 

Maybe I'm getting a little to sensitive after the mod but is the rpm needle supposed to move slightly(very slightly but noticeable) when the car is idling?

 

LOL . . . That tach needle is going to drive you nuts. Yes, it does move very slightly at times.
